I'm curious how that could work. That peaks my interest because I've known people who have autism and seem great at socializing. I don't have autism, but I'm very socially awkward, and if autistic people can do that I find it inspirational for my own socializing journey.
A podcaster on Radio Free Totebag casually said it, and idk if it was just as a passing joke, or if they were speaking factually. They mentioned a therapist not liking that they still say they're autistic when it's an old diagnosis.
I don't have any knowledge of the science behind this.
Anecdotally, I was diagnosed with Asperger's when I was about 12. I'm now in my early 30s and most people can't tell, and I'd even say it personally doesn't negatively impact me much anymore. I think this maybe due to the fact I was pretty socially active in my 20s and I sort learned to "work around" or compensate over time. Or maybe I was misdiagnosed, idk.
This is 100% just my totally subjective experience and shouldn't be taken as anything beyond that.
