I don't think he's really "beating" Autism. Autism has several forms and stages. It affects people in many different ways. You have mild to severe. I think many times some people automatically assume that because one may have a mental illness or medical illness, that person lacks Intelligence. However, some studies find that many have high IQs but without proper testing and guidance the label is wrong. An example is Dyslexia.
I think many people young and old should start becoming more aware of these things and catch the signs early. What I mean is be proactive and educate others like the thread author.
Note to Parents: Pay more attention and get tests. Never take the word of anybody as it is set in stone. Never hesitate about getting a second opinion. Also, if your child is 1 yr old and is not walking or talking kid mumbo jumbo, get an evaluation immediately.
