I started at 16, 44M now, but also remember all that COM stuff, writing shell extensions for Windows 95 and stuff. And reading about it in the press (MSDN Magazine?). It was the new AI then ;)

I think you really hit the jackpot because you got a full career out of it, saw an amazing evolution etc. So you can hopefully enjoy the ride now being more as a spectator without the fear of being personally affected by job displacement. Enjoy the retirement!
