&gt;&gt; highly profitable industries<p>Something else. There&#x27;s a problem with taking profitability as a measure of the
success of an AI technique, or anything really, if for no other reason than that
profitability is transient, and much more so in technology where today&#x27;s cutting
edge is tomorrow&#x27;s dull blah. Whether a given technology is successful or not
has nothing to do with whether it works well or not; it has everything to do wth
whether the way it is marketed works or not. Otherwise MS Windows would not be
the most widely adopted OS, yeah?<p>In the end, the only thing that having a profitable industry shows is that you
have a profitable industry, nothing else. So some folks make money with machine
learning systems and they hype them a lot. That&#x27;s just marketing. If you
understand the technology you realise there&#x27;s a big difference between the hype
and the actual hands-on results.
