Do you believe in mental abilities? Do you have any?

This reminds me of the Rain Man.

Is he mentally disabled or is he mentally enhanced?

The ability to remember everything but being a bit slow...

If we could fully use our brain we could be unstoppable.

Also that mother bonding thing is instinct, penguins can recognize their hatch lings call even if they never herd it before, nature is so interesting.

is that the guy everyone thinks of when they say the word "autistic"?

there is a strong minority of high-functioning autistics that say autism is a mental advancement. if you look at the diagnostic criteria for Aspergers Syndrome (high-functioning form of autism) for example, they talk about "special interests," and Hans Asperger himself described the boys he was diagnosing as "little professors" (for girls this has been more recently adapted as "little philosophers")

it is pretty generally accepted that Aspies at least will usually have one or more very specific areas that they know a lot about, or even excel, so in that sense it is "enhanced" - but only in that particular field, the rest of their functioning can be severely limited.

personally... i would not define autism as anything but a disability, but if it's the right field of interest for that particular person, a given high-functioning autistic can be abreast or even ahead of the flock.
