>The concern is that autism as a rigorous category may be useless, but that doesn't mean that autistic people are suddenly neurotypical

IDK. I'm diagnosed as autistic, but I've become a bit less attached to that label in recent years. Like, I do struggle with eye contact, excessive noise, and social situations. I'm not going to say that I'm just a normal guy, but I do think that there's a wide spectrum here that encompasses everybody. I don't buy the idea that autism is some special category of people that are totally unlike neurotypicals. Instead, it's just one side of the spectrum, with neurotypicals on the other end, and an ambiguous group in the middle[0]. I think that once society becomes more accepting of neurodiversity, we're going to stop getting so hung up on labels like "autistic" and "neurotypical" and accept that there's a lot of nuance in the human condition.

[0] In reality, this spectrum would be multi-dimensional, but I'm choosing to describe it as a 1D line for illustrative purposes.
