He's quite clearly on the autism spectrum. When I saw him at FOSSETCON in Orlando (RIP that conference), he was.. interesting.

I will say that I was pleasantly surprised, given what I had read about him, at how he handled a question from someone who had a very severe intellectual disability; he treated his question at the Q&A as he treated everyone else's. Although he belittled my question, but that's neither here nor there.
