Some of the lower functioning people with autism have the intelligence of a baby, in which they can only scream, grab at your shirt, drool, and do other baby type stuff.
However, there are people that are autistic that are very smart, such as Bill Gates.
To people that generalize autistic kids as retarded, be quiet, because you're probably using Windows.
A lot of people are oblivious to the concept of autistic adults, only thinking of autism being about children. This is not the case and many autistic adults (such as myself) have jobs and contribute to society like everyone else, and they are not always "high functioning".
Some Autistic people want to be cured, and that's fine if it's what they really want.
However, there are plenty of autistic people who would rather not edit themselves to conform to society's narrow defintion of "normal", of which I am one. The vast majority of people know nothing about autistic people who are HAPPY the way they are, which is a shame.
Anti-cure: "It's very likely Einstein was autistic, as well as a whole host of other people throughout history. How about appreciating autistic people for they are, not who you wish they were?"
There is no cure, but with research centers like the Autism Society of The Quad Cities (Iowa/Illinois), the Autism Society of North Carolina, the National Institute of Mental Health, the National Institute of Child Health and Human Development, and the Center for the Study of Autism, there is hope in the future for a cure for this disorder in which a person has social difficulties, demands a predictable environment, has things that they are ultimately irritated by, and other characteristics and symptoms associated with this disorder. There are also milder forms of this mental/emotional condition (See Asperger's Syndrome)
I knew another autistic kid who was amazingly awesome at street fighter for snes.
