I think the autism is just due to a change in definition
I remember an early 00's documentary where autism was defined as basically being a mental toddler and having little or confused speech.
The subject of the documentary had a violent temper tantrum directed at his middle-aged mom which left quite an impact on me
Nowadays we have to pretend everyone has autism for the sake of munchhausen-by-proxy suburban wine moms
as wikipedia puts it:
"Autism is a
spectrum disorder, meaning that it can manifest very differently in each person. Because of this, there is wide variation in the support needs of autistic people. For example, some are
nonspeaking, while others have proficient
spoken language."
i.e. we have no diagnostic criteria whatsoever
Way back when autism was considered "childhood schizophrenia" and psychopathic behaviour, not "UwU I have a tick hehe!" and "I need to follow a specific schedule im so autistic teehee!"
