The big thing is that developers move to "adult" companies. The pay is less, but they get to act like grown ups, take vacations, have families... Sure the work is more boring. Who doesn't love EDI or Factory planning!!! But getting those business skills down and implementing what the accountants want is like 50% of "computer" jobs that mostly are never, ever advertized.

I'm 40 and still looking at more school and something to keep busy another 20 years after the kids move out.
