Really? I love solving problems, and I'm lucky enough to get paid to solve problems for other people. Often times the solution requires software, sometimes it doesn't.

The thing is, if I was able to quit working today I would still look for problems to solve. Sure they may be different problems, but I would still be working even in retirement.

I think you're going to see a lot of people work their entire lives because a) they really do enjoy it and b) as long as you have your brain you can keep doing knowledge work. It's not like any of us are digging coal out the ground to the point where our bodies break down.
