If you could "fix" high functioning autistic so that they could be completely normal what kind of effect might that have on scientific fields which attract such people?
I'm not sure that's an apples-to-apples comparison. Toying with the way the brain functions is quite different from repairing a physical abnormality.
I would liken curing color blindness to curing a physical ailment, not a mental one. Would you have any moral qualms about using medical science to repair the legs of a man bound to a wheelchair?
