Came here to say this. My best friends daughter is 10, and non-verbal. She can barely dress herself and can't tie her shoes. It's heartbreaking. For every Elon Must there has to be a hundreds of thousands of kids like this.
But for every kid like this there could be 10 austistic people with average or even above average IQ. Honestly I don't know but if autism is due to genetic differences then greater proportion will be with slight deviations from normal population. In fact, Elon Must said that he has Asperger's. Some prefer to avoid this label but I find it very useful to actually distinguish autistic people with average IQ (or better)…
Then my daughter was born. She's extremely low-functioning with only basic non-verbal communication (pulling me to the door means "let's go outside"; pulling me to the kitchen means "I'm hungry"). We've done PECS boards, AAC devices, ASL, etc, and she'll use them occasionally but they frustrate her. She has almost no instinct of self-preservation and a fascination with water, so will eagerly jump into a body of water if she has the chance; likewise when we go for a walk she doesn't understand that she can't just run out into traffic. Screaming and self-injury are constant and extreme.
Which is to say that I don't think she and I have the same condition. Maybe there's a common genetic basis, but her quality of life is unimaginably worse. I get annoyed often by the 'disability advocates' who more resemble me and want to speak for people like her.
