I don't even think there should be a conversation around high functioning autistics. My kid suffers from autistic catatonia. She's also extremely high functioning. I'm sorry, there is no world where I'm going to say no thanks to a cure for my daughter's body suddenly locking into place for an unknown period of time or losing the ability to speak or function randomly or hell just understand human expression without intense intervention. We can argue about their special brain powers or whatever, but all I'm seeing is that high functioning autistic have a much higher rate of self-harm and suicide. It can't be that great.
