There are studies that shows that all of those things have effects on the likelyhood of a person becoming autistic. Autism is a complex mental thought pattern that I think is best described as having “erroneous“ metacoginitive models. That is people with autism has problems “comprehending” how the mind works on a intuitive level. Not “comprehending” the mind then leads to them having a hard time following other people’s thought trains. And various other problems. Why people get in to that thought pattern differs between individuals. So “Ultimate” cause is not so easy.
