There's a whole genre of viral social media posts that amount to lumping anyone who appears to have cared quite a bit about something that's not obviously exciting (to most other people) into the autism spectrum. Especially historical figures. "This guy made tons of detailed beetle drawings and cataloged them in books! See, there have always been autistic folks, because he definitely was!"

Like I mean maybe, but also he was a bored rich aristocrat before TV was invented, and sometimes there are no parties going on or everyone's hiding in their country estates because of a cholera outbreak or whatever, and "making shitloads of drawings and organizing them" was like 50% of scientific work at the time. So. Maybe he just had a lot of time to kill.

Going by randos posting online, "liking things" and "knowing stuff" and "caring about things" are all autistic traits when present in any but the tiniest of degrees. It's ridiculous.
