No kidding, we have a guy whos on the hogher functioning autism spectrum at the office right now, he's talented, but picks up on no social cues. He will literally have a conversation with the back of your head for 10 minutes, not picking up on the fact that it's not a good time come back later. I can see this being abused easily. Boss's will think "Hey they'll work 20 hours a day if we stimulate them just so". Day in, Day out, no overtime.
