This would not be surprising. Autism is just an extreme end of the behavior spectrum, and us geeks are closer to that end than the other.

I was shy growing up, still am in some circumstances. I'm capable of tuning out *everything* around me and focusing on some interesting task for hours and hours -- forgetting to eat, sleep, whatever. My wife often complains that I live inside my head. Take those behaviors to an extreme, and you have autism.
