  <p>I think computer science is tough for several reasons - but not necessarily because of its abstractness or the interdependency of many concepts.</p>
  <p><strong>An ill-defined and overly-general field</strong></p>
  <p>Computer science is an ill-defined field of modern vintage, that has arisen primarily so that academia can study and teach topics associated with the industrial and military application of computers.</p>
  <p>Because a computer science curriculum doubles as a trade school for all kinds of professional roles in industry, there are many different demands made of it, which leads to highly general curriculums with teaching spread thinly, and with only smaller parts of the curriculum actually being relevant to any individual student/practitioner.</p>
  <p>Courses would seem easier if more specific content was taught with an appropriate amount of time allocated, but then the course would no longer be &quot;computer science&quot; but something far more specific.</p>
  <p><strong>A field poorly understood by academia</strong></p>
  <p>The concepts and their relationships, and methods of teaching them, are still not really a settled &quot;science&quot; at all.</p>
  <p>A large number of &quot;styles&quot; or &quot;philosophies&quot; of programming, for example, are often rooted in deep conceptual conflicts in the academic realm covered by computer science.</p>
  <p>And although programming languages are typically covered by &quot;computer science&quot;, few are willing to accept (for example) that the design or study of programming languages is at all &quot;scientific&quot;.</p>
  <p><strong>Poor systems of teaching</strong></p>
  <p>Another problem is that professional practitioners who are also clear thinkers and excellent communicators, are often in market demand industrially, and this typically leads to a starvation of talent in teaching and academia where salaries and conditions have deteriorated over the decades, which then exacerbates the relative shortage of well-taught students amongst the next generation.</p>
  <p>With poor pay and conditions, you then potentially end up with teachers and professors who are less suited to teaching this particular subject (and might even end up being drawn from backgrounds in adjacent fields of study, like mathematics, which are not full-square with computer science).</p>
  <p>And many of the things first taught in university computer science courses, should probably be start to be taught to primary school children. You wouldn't expect to put a student on a university physics course who hadn't learned decimal arithmetic in school yet. You wouldn't expect to put a student on a university chemistry course who hadn't heard of the atom yet. Why should a university computer science course have to cover basic binary concepts?</p>
  <p>Indeed, those who are effective as professionals are invariably self-learners, because there is a large amount of learning necessary relative to the small amount provided formally and effectively in school and university curriculums.</p>

As more types of computing degrees are offered, some of this will sort itself out over time, though I wouldn't expect to see any serious stability until the state of the field is relatively stable, and that may still be a long time coming.

Answers.Body: <h2>Conflicting Approaches</h2>
  <p>As you described it, I see a huge conflict in your goals you want to achieve. It comes down to this:</p>
  <ul>
  <li>I want to <em>study</em> or <em>know</em> (everything)</li>
  <li>I want to be <em>proficient</em> or <em>good</em> (at everything)</li>
  </ul>
  <p>The approaches are contradictory in nature and nobody would be able to achieve them.</p>
  <p><strong>Academia</strong></p>
  <p>In case 1 you stay at the theoretical level. You learn how to &quot;understand&quot; or &quot;think about&quot; computer science, what fields there are, what problems they try to solve, what algorithms there are, how to evaluate those and decide which algorithm is better than another etc. It is a very academic approach. Most likely you will never write one line of (compiling) code yourself, but probably lots of pseudo-code.</p>
  <p>You will probably stay on your own during your study/research work. You might be in contact with undergrad students etc. You most likely will publish papers on various topics and be in loose contact (via email, letters) with other peers doing research in the same fields.</p>
  <p><strong>Programming</strong></p>
  <p>In the second case, you emphasis is the &quot;doing&quot; aspect. You want to be hands-on. Know your tools like the programming language, all their quirks inside and out, know about compiler options, the IDE, how to start writing code, how to read it, how to improve it, how to deploy it etc. You won't be able to know <em>everything</em> about <em>every</em> field of computer science. You have to <em>specialize</em>.</p>
  <p>You will have to deal with a team of other developers probably who are also employed and have certain <em>roles</em> in your team (DB specialist, QA specialist, etc.).</p>
  <p><strong>&quot;Everything&quot;</strong></p>
  <p>The third important aspect to mention is the &quot;(everything)&quot; part. You can try to learn everything or to be able to do everything - but you will never be able to reach all these ideal goals. Let that sink in.</p>
  <p>There is a process of specialization involved in both approaches. You can study broad, but at some point you will know in which topics to delve into more deeply, because of interests or maybe financial incentives.</p>
  <p>You can also try <em>to be</em> good at everything, but you will quickly realize that this is impossible. The multitude of programming languages alone makes it necessary to specialize to a few of them. All the fields you mentioned are worth specializing into also.</p>
  <p>It would be a huge waste of time and energy, to be for example, a game developer, but also know everything about haskell, R, AI, data mining, quantum computing, etc. - and also, one bit of that, is 3D transformations. You won't get to success, despite your broad knowledge. Although of course, having a <em>broader</em>/<em>wide enough</em> field of knowledge does help at times.</p>
  <p><strong>Chosing a Profession</strong></p>
  <p>So, if you like to be a teacher or professor, conducting research in the <em>field</em> of computer science, then I would recommend continue studying and reading books primarily. Maybe make some experiments with a programming language you want to use in your research or courses.</p>
  <p>If you want to be a programmer, I strongly advise, find your field of profession early. Then intensify this field by practical means. Learn the relevant programming languages. And focus on <em>reuse</em> code that already solves the abundantly known problems of the field.</p>
  <p>Meaning: Don't invent the wheel twice. If there is a graphics library that covers all the 3D-transformations for you - use it and go on to the next thing. Otherwise you will always be stuck at the basic level. Use StackOverflow to learn how others came to solutions. Use Copy&amp;Paste. But also know what you are pasting there. Also learn what Refactoring is, what Unit-Tests are and how to write Clean, maintainable Code. Forget about most books and other fields of computer science, unless you need them specifically to solve your problem which has to be unique enough so nobody solved it already.</p>
  <p><strong>Time</strong></p>
  <p>Also, don't be fooled that you need to know everything <em>in order to be a programmer or computer scientist</em>. It is a process. Because you engage into the field of comp.sci and not for example into arts, politics or architecture, you <em>are</em> a computer scientist. You are at the beginner level also. But this does not mean that you won't get better at it. Give yourself the opportunity to evolve your skills over time. And with 50 or so, ask yourself again, if you are not a computer scientist or programmer.</p>

  I think computer science is tough for several reasons - but not necessarily because of its abstractness or the interdependency of many concepts.
  
  **An ill-defined and overly-general field**
  
  Computer science is an ill-defined field of modern vintage, that has arisen primarily so that academia can study and teach topics associated with the industrial and military application of computers.
  
  Because a computer science curriculum doubles as a trade school for all kinds of professional roles in industry, there are many different demands made of it, which leads to highly general curriculums with teaching spread thinly, and with only smaller parts of the curriculum actually being relevant to any individual student/practitioner.
  
  Courses would seem easier if more specific content was taught with an appropriate amount of time allocated, but then the course would no longer be "computer science" but something far more specific.
  
  **A field poorly understood by academia**
  
  The concepts and their relationships, and methods of teaching them, are still not really a settled "science" at all.
  
  A large number of "styles" or "philosophies" of programming, for example, are often rooted in deep conceptual conflicts in the academic realm covered by computer science.
  
  And although programming languages are typically covered by "computer science", few are willing to accept (for example) that the design or study of programming languages is at all "scientific".
  
  **Poor systems of teaching**
  
  Another problem is that professional practitioners who are also clear thinkers and excellent communicators, are often in market demand industrially, and this typically leads to a starvation of talent in teaching and academia where salaries and conditions have deteriorated over the decades, which then exacerbates the relative shortage of well-taught students amongst the next generation.
  
  With poor pay and conditions, you then potentially end up with teachers and professors who are less suited to teaching this particular subject (and might even end up being drawn from backgrounds in adjacent fields of study, like mathematics, which are not full-square with computer science).
  
  And many of the things first taught in university computer science courses, should probably be start to be taught to primary school children. You wouldn't expect to put a student on a university physics course who hadn't learned decimal arithmetic in school yet. You wouldn't expect to put a student on a university chemistry course who hadn't heard of the atom yet. Why should a university computer science course have to cover basic binary concepts?
  
  Indeed, those who are effective as professionals are invariably self-learners, because there is a large amount of learning necessary relative to the small amount provided formally and effectively in school and university curriculums.

  ## Conflicting Approaches
  
  As you described it, I see a huge conflict in your goals you want to achieve. It comes down to this:
  
  * I want to *study* or *know* (everything)
  * I want to be *proficient* or *good* (at everything)
  
  The approaches are contradictory in nature and nobody would be able to achieve them.

Know your tools like the programming language, all their quirks inside and out, know about compiler options, the IDE, how to start writing code, how to read it, how to improve it, how to deploy it etc. You won't be able to know *everything* about *every* field of computer science. You have to *specialize*.
  
  You will have to deal with a team of other developers probably who are also employed and have certain *roles* in your team (DB specialist, QA specialist, etc.).
  
  **"Everything"**
  
  The third important aspect to mention is the "(everything)" part. You can try to learn everything or to be able to do everything - but you will never be able to reach all these ideal goals. Let that sink in.
  
  There is a process of specialization involved in both approaches. You can study broad, but at some point you will know in which topics to delve into more deeply, because of interests or maybe financial incentives.
