No, I don't see how autism can be a gift at all. Perhaps the ones who say that autism is a gift is referring to the savant trait of autistic people that gets referred to in movies over and over again to where people think that all autistic people have this? Either way, by definition, autism is a disorder and, for some autistic people, it is far worse than just not being able to socialise. In my case, I have to deal with executive dysfunction, doing tasks in twice the time as others, reacting extremely to the smallest amount of stress, struggling doing "trivial" tasks, getting extremely overwhelmed by the hot weather during summer and so forth.
To me, autism is a curse and it cannot be anything more than that
