I think this is becoming more common.

I started programming when I was five years old, so I kind of fit the "whiz kid" profile that everybody thought all programmers would be back in the 80s. But one of the things I've noticed, is that unlike the situation, say, in Boston, where it was easy to find other former "whiz kids", when I attend tech meetups near my current city what I find is that almost all of them started programming in mid-adulthood, say mid-thirties to forties. Many of them even went to the same boot camp. But the joy and wonder they experience mirrors what I experienced at age five, poking at my Crazy Eddie's-issued VIC-20. I am utterly delighted by this discovery, as it lends further credence to the idea in my head that programming is something deeply satisfying to the human soul.
