I didn't know I had ASD until I was an adult. Growing up I just knew I was weird and different and strange and nobody liked me. I didn't know why, I just knew I was doing something wrong and I simply wasn't "normal".
I would have given literally anything to be neurotypical, for a very long time.
When I was 19, I got formally diagnosed. For a few years after I was still hoping that it would somehow be "cured" and one day I could be like everyone else. I dunno if that made me a turncoat; just someone who didn't accept who I am.
I've since come to terms with it and accepted that it's an intrinsic part of me and that I wouldn't be the same person if I didn't have ASD. Like I can imagine what my life would be like without depression; I can't even think about what my life would be if I was neurotypical. I'd be so completely different that I basically wouldn't be "me" anymore.
But I only got to that level of acceptance because life worked out for me; I learned how to effectively mask, I have a good-paying stable job in my dream field (AAA game development), a significant other, and even a couple friends.
From what I can tell, Elon may have money but he's miserable. I can see a world in which he blames ASD for his misery (like I once did), and I can see how wanting to "cure" it makes him think that maybe he'd be happier. That's probably why he's killing monkeys with brain chips.
