This is slightly tangential, but bear with me. I'm mid-50's, and when I started programming it was a weird thing. I'd say I was a computer programmer, and I might have been the first one that normal people had actually met. It is amazing now to see the world buried in programmers (and more being produced with people from Pakistan & etc. in Coursera's Startup Engineering). More amazing that a lot of really good work is being done. So how does it graph? Plateau or Vinge-ian take-off? Is the flocking around software apps appropriate or an over-concentration of human capital?
