Computer science isn't dead, but the way it's taught probably is. By the time you finish a four-year degree in CompSci, much of what you learned at the start is irrelevant. Let's take iOS. Four years ago it was essentially nothing. Now, devs are getting rich (or at least earning a good living) building iOS apps on - arguably - the largest mobile platform on the planet.

Why would you bother spending a mint earning an obsolete CS degree from some old fart (in their 30's :-)) to just end up as Dilbert when you could have spent those 4 years getting rich? Or at least doing something very cool. This is how kids are looking at it these days. Can't say I blame them.
