Your assumptions about me are off by a lot. (Except for me thinking of a small population, which made me reflect, thank you)

It's not you in particular. Most people, when they hear autism, intellectual disability, or developmental delay picture a drooling helpless patient wearing a helmet who barely knows he's indoors. Those guys exist, and they deserve care, but they do not represent the vast majority of disabled people.

And it’s obvious you believe it helps some people if I say “be social”.

No, I don't think it helps at all. The people who are capable of being social are already social. Some may or may not use AI but the people who are capable of hearing "be social" and acting on it are largely already social and do not totally depend on AI. The reason you're seeing "normal people" get AI psychosis is because THAT IS WHAT DISABLED PEOPLE LOOK LIKE. THEY LOOK ""NORMAL."" Vulnerable people do not have a sign on their forehead that says I'm Vulnerable. That isn't how it works.

Why is an advice “not beeing helpful” to some reason enough not to say it?

Because it's exactly like saying "you should just make more money," in my opinion.
