Those people are smart but there's a textbook to follow, a clear path to graduation. I didn't mean to start a war of the professions, I'm sure there's already a Hacker News thread for that.

My point was, you can teach yourself a half-dozen programming languages, operating systems, databases... (which is inevitable for most developers) or you could have spent that time collecting diplomas in academia. This is not really a new concept, I read it somewhere else. Any profession that demands a lot of ongoing learning, I think people will quit because the effort may not seem worth it.

I agree you have to learn the "right" things but that takes experience and strategy. That's an interesting aspect of all of this. When everybody says "iPhone" you might bet on Android. Everyone says "Google Glass" and you might bet on Unity. If you have a crystal ball, maybe you're the next Warren Buffett ;-)
