your post is just, well not at all correct.
i am what you would term HFA/aspergers, i was not diagnosed till mid teens.
I stim constantly, i have never managed to make or keep friends. I have two friendly acquaintances from school, and friendly acquaintances at my volunteering job, but I wouldn’t say they were actual friends. I wish they were my friends, im not sure.
i can only speak to people outside my immediate family, if I have a set thing to say. Like at my volunteering job, i do the till, but if someone tries to make conservation I freeze up. If anything doesn’t go as expected I need someone else to help.
i have a uni degree.
i can’t work, its too much pressure and i just can’t cope. The volunteering works as it’s no pressure, i don’t have to be there.
i did not thrive independently as an adult. I am late 20s and its just not possible.
in many ways i am exactly the same as a child, from like 2 years old through adult age.
there is no one end or the other, there are many that go from each end to the other. It’s not an either or.
also many non speaking autistic children, grow up, become speaking (on different levels depending on the child), work or go to uni or volunteering or different things. Just because a child is autistic non speaking at say 3, or even 10, doesn’t mean they will stay that way forever.
obviously there is no problem if the child never speaks, or doesn’t get to a different level. That’s just how they are. But just because they seem that way as a child doesn’t been they are like that forever. It is different for every single autistic person.
