Yeah, it’s a social construct in the sense that it’s just natural differences among humans, specifically differences that don’t as often square with societal/social norms as the average person. If society were comprised of all autistic people, you wouldn’t have the label “autism”, you’d just have “people that are the way people are.”

That said, unlike the article implies, autism is, of course, not just something everyone is choosing, making up, or using to justify not doing work.

I will note the article doesn’t technically say “everyone with autism is faking it and it’s not real”, it just implies that because a lot of people self-diagnose with it now, that must mean that the real numbers are way lower than they actually are, and that people who have autism, but don’t experience major social or productivity related issues from it, aren’t actually autistic and are just “introverted” or some other general term that could theoretically apply.
