Ever deal with an uber-nerd?

8. I don't know if he has autism.

I've wondered whether he has Aspergers, as he does seem like a stereotypical Aspergers case in some regards, but my wife minored in Child Development while working on her M.E. degree and says that if he's ASD, then it's just barely. She attributes most of his behavior to laziness and a mother who is so terrified of living alone that she's allowed him to live a life with no real expectations. He geeks out because he can.

My wife and I have already had several discussions about his future after my mother-in-law passes away (probably in this coming decade, given her health issues). It's a hell of a conundrum, as we don't make enough money to support him, he drives us both insane so moving into our house is NOT an option, and yet we don't want to see him become homeless. I have no idea what's going to happen to the guy when my mother in law isn't around to support him any longer.
