That's how I feel. I don't want to be a programmer when I'm 50, or even, preferably, when I'm 30. Trying to run to the top of a dune made of quicksand just doesn't seem like a good career move.
(Hell, every few months I find something new to feel obsolete about, usually to do with the fact that most programming nowadays seems to be web-dev and I'm just not into web-dev.)
On the other hand, I'd love to keep being a computer scientist until.... I don't even know what age. Sure, eventually I'll have a family and other priorities to take care of, but the wonderful thing about the scientific frontier is that it doesn't actually move that quickly. In science, ideas have to actually be tested and percolate through for a while before they become something ever single practitioner has to know.
