As a parent of an autistic child and an educator with many years experience working with autistic adults and children I really question this as any kind of useful explanation. It may well be true that more 'intelligent' autistic people can blend in with the general population but should they have to and who is such conformity meant to benefit? Who decides what 'normal' is when it comes to our incredibly complex neurology? The diversity of human neurology is a strength. Our brains often compensate for deficits in one area with strengths in another, we already know this. If everyone's brains worked in exactly the same way we'd be doomed as a species. This article raises far more questions than it answers and is vastly over simplified.
