should read Daniel Tammet's biography, Born on a Blue Day. Not only is he autistic, he's a savant, able to ace challenges like reciting PI to 22,000+ digits, and learning Icelandic to converse on a TV talk show... inside a week. His book is a rare gift from someone who can explain what happens in his mind when he displays his bewildering talents.
He's as empathetically connected as anyone else. He has trouble with uncertainty in how he can express those feelings, and with deficits like poor facial recognition and acute sensitivity that can sometimes turn his world into an overwhelming cacaphony. He's sweetly and hopelessly in love with his boyfriend, which of course couldn't happen to a mechanical droid, and draws confidence from his relationship that allows him a measure of ease with others.
Here's his appearance on the Letterman show that was recounted in the book:

Doing this would've once been unimaginable (he was long a solitary child), before he learned how not to be waylaid by sensory overload and fear. Even then, it took a good amount of bravery to do it, because he knew it could still go terribly wrong.
