The same points I make on every post like this.
1) College isn't for everyone.
2) The 'I'm so smart that college was a waste of time' people should have just gotten a scholarship and not paid for college. 5 out of the 5 schools I officially applied to offered me scholarships. All were in the top 50 schools for my chosen major (originally, aerospace engineering). If you are smart enough that college is a waste of time, then you are also smart enough to not have to pay for college.
3) Don't extrapolate the computer science major to others. There are better books, tutorials, and online communities for hacking than seemingly any other profession. Try to find the "O'Reilly Press" of aerospace engineering pumping out 100 books a year on every imaginable topic - it just isn't happening. Same for StackOverflow, HN, etc.
4) Don't extrapolate the software engineering profession to others. It's normal for non-CS majors to be getting software engineering jobs. I personally graduated with a mechanical engineering major and CS minor. I'm now working in software engineering. The company I just left (where I worked as a mechanical engineer) would never, ever, hire a computer science major to fill a mechanical engineering job. The only three possible majors other than ME that they would hire are math, physics, or aerospace engineering.
5) If you don't do well, college is a waste of time & money.
