Thinking autism is some kind of new emergent thing is one of the most pernicious and frustrating myths out there. For better or worse (I don't know enough to pass judgement but the vibe I pick up is its a little more worse than better) Hans Asperger is a man who did exist and did do work studying Autism. I only know his name because it was thrown around the internet as an insult. You can't lampoon his name to insult neurodivergent people on the internet and pretend Autism is some "new thing" when Hans Asperger died in Nineteen Fucking Eighty.
