Yes. But not actually for technical reasons. I program to be a part of something, to participate in a vision or shared goal. I program because the experience of creating something is (currently) the major way that I have fun with people.

If I'm working on a projects/products I care about I think I could easily do that for the rest of my life.

At times, it's the enthusiasm of others which pushes me along, while I provide technical expertise / experience. Other times I will have a silly idea of the way the world should be, and I can use that to gather others around me and make their lives better.

Programming at its best, for me, is vision enabling :) How could you ever grow out of that?
