My childhood friend was diagnosed with aspergers as an adult. I have long since lost contact with him, but his sister told me that the diagnosis gave him oddly a sense of relief. But, I then started wondering if I had noticed something, and of course there was something, but I had not named it "aspergers" in my head. I then went online, and found a psychologist with a youtube channel who also had aspergers, and he made videos (in English) about his life and his problems (I think he was Dutch). I can mention that in terms of intelligence my childhood friend is not lacking in any sense whatsoever, he has a phd, but he has struggled socially. Autism is not one thing, there is a spectrum. But you can take comfort in the fact that even though your son may not become popular, he can at least become a silicone valley tech billionaire because they all seem to have such a diagnosis.
