People who are born with disabilities did not ask to be born that way, and ridiculing someone because they have autism seems like a pretty uncaring way to feel about someone.
Not a lot of people with autism, or other disabilities are able to manage their life the way that Elon Musk has done, especially after the confusion and ridicule he suffered when he was growing up.
As far as Musk only being interested in money, I do not think that is accurate either. Even though he is unable to express himself well, especially publicly, because of his autism; he seems to show that he cares about humanity and for this world as a whole.
In fact, most of the disabled people whom I have known had some of the biggest hearts and concern for people that I have seen.
