Hah I hope not. I'm 31 and just starting my time as a stay at home dad. I sure hope the tech jobs are around for me when I make it out the other side :)
I was a stay at home dad for two years in my mid-thirties. Learned to make iPhone apps, and landed a job developing iPhone apps when my kid was two. It was my first programming job. Have been in the industry for a decade now.
