I'm not sure whether or not you want my answer: I'm diagnosed with Asperger's Syndrome, which I do know is "on the spectrum", but not quite the same as plain autism.
Anyway, my vote would be "all of the above". Not very helpful, huh? But I wouldn't say "something going wrong", just "something going differently." If there were a cure, I wouldn't go for it: without the Asperger's, I wouldn't be who I am, and I _like_ quite a few of the things about it that make me who I am, and both positive and negative, and some positive or negative or neutral depending on your viewpoint. I do wish that I had known about it when I was very young, and had had some of the "social skills training" and other training that the kids are getting now.
