I'm only 28, and I do it, too-- e.g., how will kids expand their imagination and learn about the world without only having paper books to immerse themselves in for hours at a time? How will anyone learn the basics of programming without finding QuickBASIC on an old Packard-Bell 386, playing around with Gorillas or Snakes, or entering their own code from books in the library?
I think there will be a sufficient number of hacker types around for the cynical and simple reason that corporations need to inspire kids to learn how to code so that they can hire folks in two decades. This ought to inspire a token amount of educational support and tool building so that entry-level development will always be accessible to kids.
