How do we even know that autism is not normal for a certain percentage of the population? Many seem to be extremely specialized savants who aren't outwardly social. Some are defined as autistic yet a reasonable person in the constitutional sense would find that diagnoses incomprehensible. I do not know. A do know that many want to save the world but few can even save themselves. About the only thing I am sure about in life is that we are born then spend the rest of our time dying.
