I'm not a developer (I'm a physicist), but someday I'd like to go into medical research. I like the idea of coming up with things that directly help suffering people. I hope that the problem solving skills I've acquired would prove useful. Of course, I'd need to go back to school for a few years to get up to speed first.

Unfortunately, I have too much to do still in the applied physics world. It takes too damn long to commercialize inventions. I'd love to move on to the next new thing, but there is no one you can just hand off an invention to; if you want to see it deployed and profitable it seems you have to carry it all the way yourself.
