  <ul>
  <li><strong>Physical accidents</strong>, e.g. due to industrial machinery, aircraft autopilot, self-driving cars. Especially in the case of <em>unusual situations</em> such as extreme weather or sensor failure. Typically an AI will function poorly under conditions where it has not been extensively tested.</li>
  <li><strong>Social impacts</strong> such as reducing job availability, barriers for the underprivileged wrt. loans, insurance, parole.</li>
  <li><strong>Recommendation engines</strong> are manipulating us more and more to change our behaviours (as well as reinforce our own "small world" bubbles). Recommendation engines routinely serve up inappropriate content of various sorts to young children, often because content creators (e.g. on YouTube) use the right keyword stuffing to appear to be child-friendly.</li>
  <li><strong>Political manipulation...</strong> Enough said, I think.</li>
  <li><strong>Plausible deniability of privacy invasion</strong>. Now that AI can read your email and even make phone calls for you, it's easy for someone to have humans act on your personal information and claim that they got a computer to do it.</li>
  <li><strong>Turning war into a video game</strong>, that is, replacing soldiers with machines being operated remotely by someone who is not in any danger and is far removed from his/her casualties.</li>
  <li><strong>Lack of transparency</strong>. We are trusting machines to make decisions with very little means of getting the justification behind a decision.</li>
  <li><strong>Resource consumption and pollution.</strong> This is not just an AI problem, however every improvement in AI is creating more demand for Big Data and together these ram up the need for storage, processing, and networking. On top of the electricity and rare minerals consumption, the infrastructure needs to be disposed of after its several-year lifespan.</li>
  <li><strong>Surveillance</strong> — with the ubiquity of smartphones and listening devices, there is a gold mine of data but too much to sift through every piece. Get an AI to sift through it, of course!</li>
  <li><strong>Cybersecurity</strong> — cybercriminals are increasingly leveraging AI to attack their targets.</li>
  </ul>
  
  <p>Did I mention that <em>all</em> of these are in full swing already?</p>
  
  <h1>Long Term</h1>
  
  <p>Although there is no clear line between AI and AGI, this section is more about what happens when we go further towards AGI. I see two alternatives:</p>
  
  <ul>
  <li>Either we develop AGI as a result of our improved understanding of the nature of intelligence,</li>
  <li>or we slap together something that seems to work but we don't understand very well, much like a lot of machine learning right now.</li>
  </ul>
  
  <p>In the first case, if an AI "goes rogue" we can build other AIs to outwit and neutralise it. In the second case, we can't, and we're doomed. AIs will be a new life form and we may go extinct.</p>
  
  <p>Here are some potential problems:</p>
  
  <ul>
  <li><strong>Copy and paste.</strong> One problem with AGI is that it could quite conceivably run on a desktop computer, which creates a number of problems:
  
  <ul>
  <li><strong>Script Kiddies</strong> ­— people could download an AI and set up the parameters in a destructive way. Relatedly,</li>
  <li><strong>Criminal or terrorist groups</strong> would be able to configure an AI to their liking. You don't need to find an expert on bomb making or bioweapons if you can download an AI, tell it to do some research and then give you step-by-step instructions.</li>
  <li><strong>Self-replicating AI</strong> — there are plenty of computer games about this. AI breaks loose and spreads like a virus. The more processing power, the better able it is to protect itself and spread further.</li>
  </ul></li>
  <li><strong>Invasion of computing resources</strong>. It is likely that more computing power is beneficial to an AI. An AI might buy or steal server resources, or the resources of desktops and mobile devices. Taken to an extreme, this could mean that all our devices simply became unusable which would wreak havoc on the .world immediately. It could also mean massive electricity consumption (and it would be hard to "pull the plug" because power plants are computer controlled!)</li>
  <li><strong>Automated factories.</strong> An AGI wishing to gain more of a physical presence in the world could take over factories to produce robots which could build new factories and essentially create bodies for itself.</li>
  <li>These are rather philosophical considerations, but some would argue that AI would destroy what makes us human:
  
  <ul>
  <li><strong>Inferiority.</strong> What if plenty of AI entities were smarter, faster, more reliable and more creative than the best humans?</li>
  <li><strong>Pointlessness.</strong> With robots replacing the need for physical labour and AIs replacing the need for intellectual labour, we will really have nothing to do. Nobody's going to get the Nobel Prize again because the AI will already be ahead. Why even get educated in the first place?</li>
  <li><strong>Monoculture/stagnation</strong> — in various scenarios (such as a single "benevolent dictator" AGI) society could become fixed in a perpetual pattern without new ideas or any sort of change (pleasant though it may be). Basically, <em>Brave New World.</em></li>
  </ul></li>
  </ul>
  
  <p>I think AGI is coming and we need to be mindful of these problems so that we can minimise them.</p>

Answers.Text: I said "long term" and "AGI". AGI is, by definition, well beyond sophisticated pattern recognition. And although "sophisticated pattern recognition" is far and away the most common thing used in real-world applications, there is already plenty of work in other directions (particularly problem decomposition/action planning, which IMO is the lynchpin of these types of scenarios.)

  <p>Now, imagine an AI which is sufficiently powerful. This AI will notice that if he nukes all other cookie factories, everybody has to buy cookies in his factory, making sales rise and profits higher.</p>

Answers.Body: <p>I have an example which goes in kinda the opposite direction of the public's fears, but is a very real thing, which I already see happening. It is not AI-specific, but I think it will get worse through AI. It is the problem of <strong>humans trusting the AI conclusions blindly</strong> in critical applications. </p>
  
  <p>We have many areas in which human experts are supposed to make a decision. Take for example medicine - should we give medication X or medication Y? The situations I have in mind are frequently complex problems (in the Cynefin sense) where it is a really good thing to have somebody pay attention very closely and use lots of expertise, and the outcome really matters. </p>
  
  <p>There is a demand for medical informaticians to write decision support systems for this kind of problem in the medicine (and I suppose for the same type in other domains). They do their best, but the expectation is always that a human expert will always consider the system's suggestion just as one more opinion when making the decision. In many cases, it would be irresponsible to promise anything else, given the state of knowledge and the resources available to the developers. A typical example would be the use of computer vision in radiomics: a patient gets a CT scan and the AI has to process the image and decide whether the patient has a tumor. </p>
  
  <p>Of course, the AI is not perfect. Even when measured against the gold standard, it never achieves 100% accuracy. And then there are all the cases where it performs well against its own goal metrics, but the problem was so complex that the goal metric doesn't capture it well - I can't think of an example in the CT context, but I guess we see it even here on SE, where the algorithms favor popularity in posts, which is an imperfect proxy for factual correctness. </p>
  
  <p>You were probably reading that last paragraph and nodding along, "Yeah, I learned that in the first introductory ML course I took". Guess what? Physicians never took an introductory ML course. They rarely have enough statistic literacy to understand the conclusions of papers appearing in medical journals. When they are talking to their 27th patient, 7 hours into their 16 hour shift, hungry and emotionally drained, and the CT doesn't look all that clear-cut, but the computer says "it's not a malignancy", they don't take ten more minutes to concentrate on the image more, or look up a textbook, or consult with a colleague. They just go with what the computer says, grateful that their cognitive load is not skyrocketing yet again. So they turn from being experts to being people who read something off a screen. Worse, in some hospitals the administration does not only trust computers, it also has found out that they are convenient scapegoats. So, a physician has a bad hunch which goes against the computer's output, it becomes difficult for them to act on that hunch and defend themselves that they chose to overrode the AI's opinion. </p>
  
  <p>AIs are powerful and useful tools, but there will always be tasks where they can't replace the toolwielder. </p>

Answers.Text: If you're looking for more examples, the controversy around using machine learning to predict reoffending rates of applicants for bail or parole is a good one. I agree that we shouldn't expect doctors and judges to have the levels of statistical expertise needed to understand AI, in addition to their medical and legal expertise. AI designers should be aware of the fallibility of their algorithms, and provide clear guidance to its users. Maybe tell the doctor where to look on the CT scan instead of directly giving them the result.

Answers.Body: <p>This only intents to be a complement to other answers so I will not discuss to possibility of AI trying to willingly enslave humanity.</p>
  
  <p>But a different risk is already here. I would call it <em>unmastered technology</em>. I have been teached science and technology, and IMHO, AI has <em>by itself</em> no notion of good and evil, nor freedom. But it is built and used by human beings and because of that non rational behaviour can be involved.</p>
  
  <p>I would start with a real life example more related to general IT than to AI. I will speak of viruses or other malwares. Computers are rather stupid machines that are good to quickly process data. So most people rely on them. An some (bad) people develop malwares that will disrupt the correct behaviour of computers. And we all know that they can have terrible effects on small to medium organizations that are not well prepared to an computer loss.</p>
  
  <p>AI is computer based so it is vulnerable to computer type attacks. Here my example would be an AI driven car. The technology is almost ready to work. But imagine the effect of a malware making the car trying to attack other people on the road. Even without a direct access to the code of the AI, it can be attacked by <em>side channels</em>. For example it uses cameras to read signal signs. But because of the way machine learning is implemented, AI generaly does not analyses a scene the same way a human being does. Researchers have shown that it was possible to change a sign in a way that a normal human will still see the original sign, but an AI will see a different one. Imagine now that the sign is the road priority sign...</p>
  
  <p>What I mean is that even if the AI has no evil intents, bad guys can try to make it behave badly. And to more important actions will be delegated to AI (medecine, cars, planes, not speaking of bombs) the higher the risk. Said differently, I do not really fear the AI for itself, but for the way it can be used by humans.</p>

Answers.Body: <p>I think one of the most real (ie. related to current, existing AIs) risks are in blindly relying on unsupervised AIs, for two reasons.</p>
  
  <h3>1. AI systems may degrade</h3>
  
  <p>Physical error in AI systems may start producing wildly wrong results in regions in which they were not tested for because the physical system starts providing wrong values. This is sometimes redeemed by self-testing and redundancy, but still requires occasional human supervision.</p>
  
  <p>Self learning AIs also have a software weakness - their weight networks or statistic representations may approach local minima where they are stuck with one wrong result.</p>
  
  <h3>2. AI systems are biased</h3>
  
  <p>This is fortunately frequently discussed, but worth mentioning: AI systems' classification of inputs is often biased because the training/testing dataset were biased as well. This results in AIs not recognizing people of certain ethnicity, for more obvious example. However there are less obvious cases that may only be discovered after some bad accident, such as AI not recognizing certain data and accidentally starting fire in a factory, breaking equipment or hurting people.</p>

Answers.Text: This is a good, contemporary answer. "Black box" AI such as neural networks are impossible to test in an absolute manner, which makes them less than 100% predictable - and by extension, less than 100% reliable. We never know when an AI will develop an alternative strategy to a given problem, and how this alternative strategy will affect us, and this is a really huge issue if we want to rely on AI for important tasks like driving cars or managing resources.

Answers.Body: <p>Human beings currently exist in an ecological-economic niche of "the thing that thinks".</p>
  
  <p>AI is also a thing that thinks, so it will be invading our ecological-economic niche.  In both ecology and economics, having something else occupy your niche is not a great plan for continued survival.</p>
  
  <p>How exactly Human survival is compromised by this is going to be pretty chaotic.  There are going to be a bunch of plausible ways that AI could endanger human survival as a species, or even as a dominant life form.</p>
  
  <hr>
  
  <p>Suppose there is a strong AI without "super ethics" which is cheaper to manufacture than a human (including manufacturing a "body" or way of manipulating the world), and as smart or smarter than a human.</p>
  
  <p>This is a case where we start competing with that AI for resources.  It will happen on microeconomic scales (do we hire a human, or buy/build/rent/hire an AI to solve this problem?).  Depending on the rate at which AIs become cheap and/or smarter than people, this can happen slowly (maybe an industry at a time) or extremely fast.</p>
  
  <p>In a capitalist competition, those that don't move over to the cheaper AIs end up out-competed.</p>
  
  <p>Now, in the short term, if the AI's advantages are only marginal, the high cost of educating humans for 20-odd years before they become productive could make this process slower.  In this case, it might be worth paying a Doctor above starvation wages to diagnose disease instead of an AI, but it probably isn't worth paying off their student loans.  So new human Doctors would rapidly stop being trained, and existing Doctors would be impoverished.  Then over 20-30 years AI would completely replace Doctors for diagnostic purposes.</p>
  
  <p>If the AI's advantages are large, then it would be rapid.  Doctors wouldn't even be worth paying poverty level wages to do human diagnostics.  You can see something like that happening with muscle-based farming when gasoline-based farming took over.</p>
  
  <p>During past industrial revolutions, the fact that humans where able to think means that you could repurpose surplus human workers to do other actions; manufacturing lines, service economy jobs, computer programming, etc.  But in this model, AI is cheaper to train and build and as smart or smarter than humans at that kind of job.</p>
  
  <p>As evidenced by the ethanol-induced Arab spring, crops and cropland can be used to fuel both machines and humans.  When machines are more efficient in terms of turning cropland into useful work, you'll start seeing the price of food climb.  This typically leads to riots, as people really don't like starving to death and are willing to risk their own lives to overthrow the government in order to prevent this.</p>
  
  <p>You can mollify the people by providing subsidized food and the like.  So long as this isn't economically crippling (ie, if expensive enough, it could result in you being out-competed by other places that don't do this), this is merely politically unstable.</p>
  
  <p>As an alternative, in the short term, the ownership caste who is receiving profits from the increasingly efficient AI-run economy can pay for a police or military caste to put down said riots.  This requires that the police/military castes be upper lower to middle class in standards of living, in order to ensure continued loyalty -- you don't want them joining the rioters.</p>
  
  <p>So one of the profit centers you can put AI towards is AI based military and policing.  Drones that deliver lethal and non-lethal ordnance based off of processing visual and other data feeds can reduce the number of middle-class police/military needed to put down food-price triggered riots or other instability.  As we have already assumed said AIs can have bodies and training cheaper than a biological human, this can also increase the amount of force you can deploy per dollar spent.</p>
  
  <p>At this point, we are talking about a mostly AI run police and military being used to keep starving humans from overthrowing the AI run economy and seizing the means of production from the more efficient use it is currently being put to.</p>
  
  <p>The vestigial humans who "own" the system at the top are making locally rational decisions to optimize their wealth and power.  They may or may not persist for long; so long as they drain a relatively small amount of resources and don't mess up the AI run economy, there won't be much selection pressure to get rid of them.  On the other hand, as they are contributing nothing of value, they position "at the top" is politically unstable.</p>
  
  <p>This process assumed a "strong" general AI.  Narrower AIs can pull this off in pieces.  A cheap, effective diagnostic computer could reduce most Doctors into poverty in a surprisingly short period of time, for example.  Self driving cars could swallow 5%-10% of the economy.  Information technology is already swallowing the retail sector with modest AI.</p>
  
  <p>It is said that every technological advancement leads to more and better jobs for humans.  And this has been true for the last 300+ years.</p>
  
  <p>But prior to 1900, it was also true that every technological advancement led to more and better jobs for horses.  Then the ICE and automobile arrived, and now there are far fewer working horses; the remaining horses are basically the equivalent of human personal servants: kept for the novelty of "wow, cool, horse" and the fun of riding and controlling a huge animal.</p>

  <p>This is the type of AI that your question is referring to. A super-intelligent conscious AI that will destroy/enslave humanity. This is mostly brought to us by science-fiction. Some notable Hollywood examples are <em>"The terminator"</em>, <em>"The Matrix"</em>, <em>"Age of Ultron"</em>. The most influential novels were written by Isaac Asimov and are referred to as the <em>"Robot series"</em> (which includes <em>"I, robot"</em>, which was also adapted as a movie).</p>
  
  <p>The basic premise under most of these works are that AI will evolve to a point where it becomes conscious and will surpass humans in intelligence. While Hollywood movies mainly focus on the robots and the battle between them and humans, not enough emphasis is given to the actual AI (i.e. the "brain" controlling them). As a side note, because of the narrative, this AI is usually portrayed as supercomputer controlling everything (so that the protagonists have a specific target). Not enough exploration has been made on "ambiguous intelligence" (which I think is more realistic).</p>
  
  <p>In the real world, AI is focused on solving specific tasks! An AI agent that is capable of solving problems from different domains (e.g. understanding speech and processing images and driving and ... - like humans are) is referred to as General Artificial Intelligence and is required for AI being able to "think" and become conscious.  </p>
  
  <p>Realistically, we are a <strong>loooooooong way</strong> from General Artificial Intelligence! That being said there is <strong>no evidence</strong> on why this <strong>can't</strong> be achieved in the future. So currently, even if we are still in the infancy of AI, we have no reason to believe that AI won't evolve to a point where it is more intelligent than humans.</p>
  
  <h2>Using AI with malicious intent</h2>
  
  <p>Even though an AI conquering the world is a long way from happening there are <strong>several reasons to be concerned with AI today</strong>, that don't involve robots!

  ## tl;dr
  
  There are many **valid** reasons why people might fear (or better *be concerned about*) AI, not all involve robots and apocalyptic scenarios.
  
  To better illustrate these concerns, I'll try to split them into three categories.
  
  ## Conscious AI
  
  This is the type of AI that your question is referring to. A super-intelligent conscious AI that will destroy/enslave humanity. This is mostly brought to us by science-fiction.

  ## Using AI with malicious intent
  
  Even though an AI conquering the world is a long way from happening there are **several reasons to be concerned with AI today**, that don't involve robots!
  The second category I want to focus a bit more on is several malicious uses of today's AI.
  
  I'll focus only on **AI applications that are available today**. Some examples of AI that can be used for malicious intent:

Even though when we think of mass surveillance we think of China, many western cities like [London](https://www.cctv.co.uk/how-many-cctv-cameras-are-there-in-london/), [Atlanta](https://cloudtweaks.com/2019/09/mass-surveillance-adversarial-ai-in-atlanta/) and Berlin are among the [most-surveilled cities in the world](https://www.comparitech.com/vpn-privacy/the-worlds-most-surveilled-cities/). China has taken things a step further by adopting the [social credit system](https://futurism.com/china-social-credit-system-rate-human-value), an evaluation system for civilians which seems to be taken straight out of the pages of George Orwell's 1984.

  # Short term
  
  * **Physical accidents**, e.g. due to industrial machinery, aircraft autopilot, self-driving cars. Especially in the case of *unusual situations* such as extreme weather or sensor failure. Typically an AI will function poorly under conditions where it has not been extensively tested.
  * **Social impacts** such as reducing job availability, barriers for the underprivileged wrt. loans, insurance, parole.
  * **Recommendation engines** are manipulating us more and more to change our behaviours (as well as reinforce our own "small world" bubbles). Recommendation engines routinely serve up inappropriate content of various sorts to young children, often because content creators (e.g. on YouTube) use the right keyword stuffing to appear to be child-friendly.
  * **Political manipulation...** Enough said, I think.
  * **Plausible deniability of privacy invasion**. Now that AI can read your email and even make phone calls for you, it's easy for someone to have humans act on your personal information and claim that they got a computer to do it.
  * **Turning war into a video game**, that is, replacing soldiers with machines being operated remotely by someone who is not in any danger and is far removed from his/her casualties.
  * **Lack of transparency**. We are trusting machines to make decisions with very little means of getting the justification behind a decision.
  * **Resource consumption and pollution.** This is not just an AI problem, however every improvement in AI is creating more demand for Big Data and together these ram up the need for storage, processing, and networking. On top of the electricity and rare minerals consumption, the infrastructure needs to be disposed of after its several-year lifespan.
  * **Surveillance** — with the ubiquity of smartphones and listening devices, there is a gold mine of data but too much to sift through every piece. Get an AI to sift through it, of course!
  * **Cybersecurity** — cybercriminals are increasingly leveraging AI to attack their targets.
  
  Did I mention that *all* of these are in full swing already?
  
  # Long Term
  
  Although there is no clear line between AI and AGI, this section is more about what happens when we go further towards AGI. I see two alternatives:
  
  * Either we develop AGI as a result of our improved understanding of the nature of intelligence,
  * or we slap together something that seems to work but we don't understand very well, much like a lot of machine learning right now.
  
  In the first case, if an AI "goes rogue" we can build other AIs to outwit and neutralise it. In the second case, we can't, and we're doomed. AIs will be a new life form and we may go extinct.
  
  Here are some potential problems:
  
  * **Copy and paste.** One problem with AGI is that it could quite conceivably run on a desktop computer, which creates a number of problems:
    + **Script Kiddies** ­— people could download an AI and set up the parameters in a destructive way. Relatedly,
    + **Criminal or terrorist groups** would be able to configure an AI to their liking. You don't need to find an expert on bomb making or bioweapons if you can download an AI, tell it to do some research and then give you step-by-step instructions.
    + **Self-replicating AI** — there are plenty of computer games about this. AI breaks loose and spreads like a virus. The more processing power, the better able it is to protect itself and spread further.
  * **Invasion of computing resources**. It is likely that more computing power is beneficial to an AI. An AI might buy or steal server resources, or the resources of desktops and mobile devices. Taken to an extreme, this could mean that all our devices simply became unusable which would wreak havoc on the .world immediately. It could also mean massive electricity consumption (and it would be hard to "pull the plug" because power plants are computer controlled!)
  * **Automated factories.** An AGI wishing to gain more of a physical presence in the world could take over factories to produce robots which could build new factories and essentially create bodies for itself.
  * These are rather philosophical considerations, but some would argue that AI would destroy what makes us human:
    + **Inferiority.** What if plenty of AI entities were smarter, faster, more reliable and more creative than the best humans?
    + **Pointlessness.** With robots replacing the need for physical labour and AIs replacing the need for intellectual labour, we will really have nothing to do. Nobody's going to get the Nobel Prize again because the AI will already be ahead. Why even get educated in the first place?
    + **Monoculture/stagnation** — in various scenarios (such as a single "benevolent dictator" AGI) society could become fixed in a perpetual pattern without new ideas or any sort of change (pleasant though it may be). Basically, *Brave New World.*
  
  I think AGI is coming and we need to be mindful of these problems so that we can minimise them.
  
  > **Comments:**
  > **username_3**: I think the kind of AI that's capable of reprogramming factories to build robots for itself is a long way away. Modern "AI" is just really sophisticated pattern recognition.  
  > **username_2**: I said "long term" and "AGI". AGI is, by definition, well beyond sophisticated pattern recognition. And although "sophisticated pattern recognition" is far and away the most common thing used in real-world applications, there is already plenty of work in other directions (particularly problem decomposition/action planning, which IMO is the lynchpin of these types of scenarios.)

  In addition to the other answers, I would like to add to nuking cookie factory example:
  
  Machine learning AIs basically try to fulfill a goal described by humans. For example, humans create an AI running a cookie factory. The goal they implement is to sell as many cookies as possible for the highest profitable margin.
  
  Now, imagine an AI which is sufficiently powerful. This AI will notice that if he nukes all other cookie factories, everybody has to buy cookies in his factory, making sales rise and profits higher.
  
  So, the human error here is giving no penalty for using violence in the algorithm. This is easily overlooked because humans didn't expect the algorithm to come to this conclusion.

  > **username_5**: This reminds me of a real-world example I saw on reddit once where someone was training an AI to climb some stairs in Unity. It discovered that it could press itself into the ground with a lot of force and the physics would glitch, causing it to fly into the air and be the fastest to the top.  
  > **username_6**: Or, worse, it'd decide that humans are made out of atoms that would be better used to make cookies out of.  
  > **username_7**: I've heard this argument before. One of the fallacies of predicting an AI doomsday is that we can't predict what the AI will do. It's entirely possible the AI would recognize that nuking other cookie companies might throw off the global economy and destroy any potential demand for cookies...

  My favorite scenario for harm by AI involves not high intelligence, but low intelligence. Specifically, the [grey goo](https://en.wikipedia.org/wiki/Gray_goo) hypothesis.
  
  This is where a self-replicating, automated process runs amok and converts all resources into copies of itself.
  
  The point here is that the AI is not "smart" in the sense of having high intelligence or general intelligence--it is merely very good at a single thing and has the ability to replicate exponentially.
  
  > **Comments:**
  > **username_3**: FWIW, humans are already grey goo. We're selfish grey goo that doesn't want to be replaced by an even more efficient grey goo.

  > **username_16**: @immibis Did you read the [gray goo article on Wikipedia](https://en.wikipedia.org/wiki/Gray_goo) that this answer references? The term refers to unintelligent (nano)machines going amok, not to any intelligent behavior. So I'd say, no, humans are not it (and neither is AI), since we didn't eat Albert Einstein when we could.  
  > **username_14**: @username_16 the fundamental meaning of term "intelligence" seems widely misunderstood, both in academia and the general public.  Intelligence is a spectrum, generally relative (to other decision-making mechanisms), and is based on the utility of any given decision in the context of a problem.  So grey goo would be intelligent, just that the intelligence would be limited and narrow.

  I have an example which goes in kinda the opposite direction of the public's fears, but is a very real thing, which I already see happening. It is not AI-specific, but I think it will get worse through AI. It is the problem of **humans trusting the AI conclusions blindly** in critical applications.
  
  We have many areas in which human experts are supposed to make a decision. Take for example medicine - should we give medication X or medication Y? The situations I have in mind are frequently complex problems (in the Cynefin sense) where it is a really good thing to have somebody pay attention very closely and use lots of expertise, and the outcome really matters.
  
  There is a demand for medical informaticians to write decision support systems for this kind of problem in the medicine (and I suppose for the same type in other domains). They do their best, but the expectation is always that a human expert will always consider the system's suggestion just as one more opinion when making the decision. In many cases, it would be irresponsible to promise anything else, given the state of knowledge and the resources available to the developers. A typical example would be the use of computer vision in radiomics: a patient gets a CT scan and the AI has to process the image and decide whether the patient has a tumor.
  
  Of course, the AI is not perfect. Even when measured against the gold standard, it never achieves 100% accuracy. And then there are all the cases where it performs well against its own goal metrics, but the problem was so complex that the goal metric doesn't capture it well - I can't think of an example in the CT context, but I guess we see it even here on SE, where the algorithms favor popularity in posts, which is an imperfect proxy for factual correctness.
  
  You were probably reading that last paragraph and nodding along, "Yeah, I learned that in the first introductory ML course I took". Guess what? Physicians never took an introductory ML course. They rarely have enough statistic literacy to understand the conclusions of papers appearing in medical journals. When they are talking to their 27th patient, 7 hours into their 16 hour shift, hungry and emotionally drained, and the CT doesn't look all that clear-cut, but the computer says "it's not a malignancy", they don't take ten more minutes to concentrate on the image more, or look up a textbook, or consult with a colleague. They just go with what the computer says, grateful that their cognitive load is not skyrocketing yet again. So they turn from being experts to being people who read something off a screen. Worse, in some hospitals the administration does not only trust computers, it also has found out that they are convenient scapegoats. So, a physician has a bad hunch which goes against the computer's output, it becomes difficult for them to act on that hunch and defend themselves that they chose to overrode the AI's opinion.
  
  AIs are powerful and useful tools, but there will always be tasks where they can't replace the toolwielder.
  
  > **Comments:**
  > **username_9**: If you're looking for more examples, the controversy around using machine learning to predict reoffending rates of applicants for bail or parole is a good one. I agree that we shouldn't expect doctors and judges to have the levels of statistical expertise needed to understand AI, in addition to their medical and legal expertise. AI designers should be aware of the fallibility of their algorithms, and provide clear guidance to its users. Maybe tell the doctor where to look on the CT scan instead of directly giving them the result.

  This only intents to be a complement to other answers so I will not discuss to possibility of AI trying to willingly enslave humanity.
  
  But a different risk is already here. I would call it *unmastered technology*. I have been teached science and technology, and IMHO, AI has *by itself* no notion of good and evil, nor freedom. But it is built and used by human beings and because of that non rational behaviour can be involved.
  
  I would start with a real life example more related to general IT than to AI. I will speak of viruses or other malwares. Computers are rather stupid machines that are good to quickly process data. So most people rely on them. An some (bad) people develop malwares that will disrupt the correct behaviour of computers. And we all know that they can have terrible effects on small to medium organizations that are not well prepared to an computer loss.
  
  AI is computer based so it is vulnerable to computer type attacks. Here my example would be an AI driven car. The technology is almost ready to work. But imagine the effect of a malware making the car trying to attack other people on the road. Even without a direct access to the code of the AI, it can be attacked by *side channels*. For example it uses cameras to read signal signs. But because of the way machine learning is implemented, AI generaly does not analyses a scene the same way a human being does. Researchers have shown that it was possible to change a sign in a way that a normal human will still see the original sign, but an AI will see a different one. Imagine now that the sign is the road priority sign...
  
  What I mean is that even if the AI has no evil intents, bad guys can try to make it behave badly. And to more important actions will be delegated to AI (medecine, cars, planes, not speaking of bombs) the higher the risk. Said differently, I do not really fear the AI for itself, but for the way it can be used by humans.

  Physical error in AI systems may start producing wildly wrong results in regions in which they were not tested for because the physical system starts providing wrong values. This is sometimes redeemed by self-testing and redundancy, but still requires occasional human supervision.
  
  Self learning AIs also have a software weakness - their weight networks or statistic representations may approach local minima where they are stuck with one wrong result.
  
  ### 2. AI systems are biased
  
  This is fortunately frequently discussed, but worth mentioning: AI systems' classification of inputs is often biased because the training/testing dataset were biased as well. This results in AIs not recognizing people of certain ethnicity, for more obvious example. However there are less obvious cases that may only be discovered after some bad accident, such as AI not recognizing certain data and accidentally starting fire in a factory, breaking equipment or hurting people.
  
  > **Comments:**
  > **username_13**: This is a good, contemporary answer. "Black box" AI such as neural networks are impossible to test in an absolute manner, which makes them less than 100% predictable - and by extension, less than 100% reliable. We never know when an AI will develop an alternative strategy to a given problem, and how this alternative strategy will affect us, and this is a really huge issue if we want to rely on AI for important tasks like driving cars or managing resources.

  Human beings currently exist in an ecological-economic niche of "the thing that thinks".
  
  AI is also a thing that thinks, so it will be invading our ecological-economic niche. In both ecology and economics, having something else occupy your niche is not a great plan for continued survival.
  
  How exactly Human survival is compromised by this is going to be pretty chaotic. There are going to be a bunch of plausible ways that AI could endanger human survival as a species, or even as a dominant life form.

  Suppose there is a strong AI without "super ethics" which is cheaper to manufacture than a human (including manufacturing a "body" or way of manipulating the world), and as smart or smarter than a human.
  
  This is a case where we start competing with that AI for resources. It will happen on microeconomic scales (do we hire a human, or buy/build/rent/hire an AI to solve this problem?). Depending on the rate at which AIs become cheap and/or smarter than people, this can happen slowly (maybe an industry at a time) or extremely fast.
  
  In a capitalist competition, those that don't move over to the cheaper AIs end up out-competed.
  
  Now, in the short term, if the AI's advantages are only marginal, the high cost of educating humans for 20-odd years before they become productive could make this process slower. In this case, it might be worth paying a Doctor above starvation wages to diagnose disease instead of an AI, but it probably isn't worth paying off their student loans. So new human Doctors would rapidly stop being trained, and existing Doctors would be impoverished. Then over 20-30 years AI would completely replace Doctors for diagnostic purposes.
  
  If the AI's advantages are large, then it would be rapid. Doctors wouldn't even be worth paying poverty level wages to do human diagnostics. You can see something like that happening with muscle-based farming when gasoline-based farming took over.
  
  During past industrial revolutions, the fact that humans where able to think means that you could repurpose surplus human workers to do other actions; manufacturing lines, service economy jobs, computer programming, etc. But in this model, AI is cheaper to train and build and as smart or smarter than humans at that kind of job.
  
  As evidenced by the ethanol-induced Arab spring, crops and cropland can be used to fuel both machines and humans. When machines are more efficient in terms of turning cropland into useful work, you'll start seeing the price of food climb. This typically leads to riots, as people really don't like starving to death and are willing to risk their own lives to overthrow the government in order to prevent this.
  
  You can mollify the people by providing subsidized food and the like. So long as this isn't economically crippling (ie, if expensive enough, it could result in you being out-competed by other places that don't do this), this is merely politically unstable.
  
  As an alternative, in the short term, the ownership caste who is receiving profits from the increasingly efficient AI-run economy can pay for a police or military caste to put down said riots. This requires that the police/military castes be upper lower to middle class in standards of living, in order to ensure continued loyalty -- you don't want them joining the rioters.
  
  So one of the profit centers you can put AI towards is AI based military and policing. Drones that deliver lethal and non-lethal ordnance based off of processing visual and other data feeds can reduce the number of middle-class police/military needed to put down food-price triggered riots or other instability. As we have already assumed said AIs can have bodies and training cheaper than a biological human, this can also increase the amount of force you can deploy per dollar spent.
  
  At this point, we are talking about a mostly AI run police and military being used to keep starving humans from overthrowing the AI run economy and seizing the means of production from the more efficient use it is currently being put to.
  
  The vestigial humans who "own" the system at the top are making locally rational decisions to optimize their wealth and power. They may or may not persist for long; so long as they drain a relatively small amount of resources and don't mess up the AI run economy, there won't be much selection pressure to get rid of them. On the other hand, as they are contributing nothing of value, they position "at the top" is politically unstable.
  
  This process assumed a "strong" general AI. Narrower AIs can pull this off in pieces. A cheap, effective diagnostic computer could reduce most Doctors into poverty in a surprisingly short period of time, for example. Self driving cars could swallow 5%-10% of the economy. Information technology is already swallowing the retail sector with modest AI.
  
  It is said that every technological advancement leads to more and better jobs for humans. And this has been true for the last 300+ years.
  
  But prior to 1900, it was also true that every technological advancement led to more and better jobs for horses. Then the ICE and automobile arrived, and now there are far fewer working horses; the remaining horses are basically the equivalent of human personal servants: kept for the novelty of "wow, cool, horse" and the fun of riding and controlling a huge animal.

  AI that is used to solve a real world problem could pose a risk to humanity and doesn't exactly require sentience, this also requires a degree of human stupidity too..
  
  Unlike humans, an AI would find the most logical answer without the constraint of emotion, ethics, or even greed... Only logic. Ask this AI how to solve a problem that humans created (for example, Climate Change) and it's solution might be to eliminate the entirety of the human race to protect the planet. Obviously this would require giving the AI the ability to act upon it's outcome which brings me to my earlier point, human stupidity.

  In addtion to the many answers already provided, I would bring up the issue of [***adversarial examples***](https://arxiv.org/pdf/1607.02533.pdf) in the area of image models.
  
  Adversarial examples are images that have been perturbed with specifically designed noise that is often imperceptible to a human observer, but strongly alters the prediction of a model.
  
  Examples include:
  
  * Affecting the predicted diagnosis in a [chest x-ray](https://arxiv.org/pdf/1804.05296.pdf)
  * Affecting the [detection of roadsigns](https://arxiv.org/pdf/1807.07769.pdf) necessary for autonomous vehicles.

  Artificial intelligence can harm us in any of the ways of natural intelligence (of humans). The distinction between natural and artificial intelligence will vanish when humans start augmenting themselves more intimately. Intelligence may no longer characterize the identity and will become a limitless possession. The harm caused will be as much the humans can endure for preserving their evolving self-identity.

  Few people realize that our global economy should be considered an AI:
  - The money transactions are the signals over a neural net. The nodes in the neural net would be the different corporations or private persons paying or receiving money.
  - It is man-made so qualifies as artificial
  
  This neural network is better in its task then humans:
  Capitalism has always won against economy planned by humans (plan-economy).
  
  Is this neural net dangerous ?
  Might differ if you are the CEO earning big versus a fisherman in a river polluted by corporate waste.
  
  How did this AI become dangerous?
  You could answer it is because of human greed.
  Our creation reflects ourselves.
  In other words: we didnot train our neural net to behave well.
  Instead of training the neural net to improve living quality for all humans, we trained it to make rich fokes more rich.
  
  Would it be easy to train this AI to be no longer dangerous ?
  Maybe not, maybe some AI are just larger then life.
  It is just survival of the fittest.
