I'm mildly autistic and I like the way I am. Really. I don't consider it a disability at all; it's got pros and cons, but for every thing that I'm worse at than a "normal" person, I feel there's something else equally valuable I'm better at, so it balances out as a slight positive for me and a big positive for humanity because, as the OP alluded to, diversity enables specialisation.
The issue is of course some people genuinely experience autism as a disability, and the more severe it is, the more likely that is to be the case. But you can make a solid argument that autism is not necessarily disability: like height, gigantism is unhealthy, but being tall can be adaptive!
There is a movement in neurodivergence trying to define autism as a different human experience, rather than in the framing of a disability, but this is still controversial within autism advocate circles.
However, I’d much rather not have to deal with it in the first place, and if I could be changed, I’d happily change.
If we can avoid future generations having to deal with it at this same relatively high rate, great.
