There's a lot more to autism than learning social queues. In many cases it comes with neurotransmitter differences or completely differently formed amygdala which often means emotional regulation issues and sensory overload. And while there are treatment options you can't learn your way or willpower your way out of a differently configured brain. And trying to conceal autistic symptoms (known as masking) is extremely tiring if you can even do it at all. So expecting some patience and acceptance of non-neurotypical behavior is a must. And total independence or not needing disability care is sometimes just not possible.
There's a spectrum. Sometimes autistic people can blend with neurotypicals more or less seamlessly but sometimes that isn't the case.
Well you know, all people of all types have different outcomes, some good and some bad. My younger brother, who is 10 years younger, also apparently has autism, though there is marked difference in his manifestation of symptoms, to mine. For example, his motor coordination is such that he doesn't do many things with dynamic variability - he shuts doors/walks hard, for example, whereas I am gentle. His voice is markedly monotone in character, whereas I talk with a dynamic capacity. But he is also way more social than I am
And he is also more prone to aggressive behavior, unfortunately, and that could possibly be from the influence of his friends, and of his choice to go drinking. For example, he once kicked some furniture so hard that he broke his foot, and had to wear a cast for many months.
But besides that, there are some examples, I think, of people probably strengthening the internal world they have, probably to the point where they supersede the ability of neurotypicals. I take for example, the youtuber vaush. He said that they wanted to send him to a special school for autism, but that didn't happen. He talks well of his parents though, and says he was raised in hollywood, surely without a lot of privation. He is loquacious in a way that anyone could envy, having developed an idiosyncratically powerful personality
That's not to say that I agree with many of his conclusions, as I don't, but I recognize the sheer force of his personality, and obvious success.
