Wasn’t this always the case?

We don't have a cure for autism.

We don't have a prevention for autism.

We don't have a clear cause for autism beyond recognizing that genetics play a role.

We don't even have a clear picture of the scope; one reason rates appear to be increasing is simply that we've gotten better at recognizing symptoms in previously ignored populations. But... We are probably still ignoring symptoms in some significant populations.

It is completely understandable that, as we learn more and the scope of the problem becomes more apparent, folks are alarmed and clamoring for politicians to Do Something.

...it is less apparent that there is anything productive to be done, beyond continued efforts to better understand the situation.

We (as a society) and Kennedy in particular (within his own family), have ample experience with the harms wrought by efforts to Do Something when no effective solution exists.

The diagnosis of autism grow, but mostly because a lot more people are diagnosed with autism. I don't like that sentence, but modern autism is more of a social construct than what autism used to be.

'on the spectrum' is probably to me a big lie. I've worked (as a counsellor) with genuine autistic people, non-communicative or not, and frankly if you've learned to mask and to lie on your own, with intent (I did) or naturally (most people do), you shouldn't be considered autistic. Or at least you shouldn't hide behind your diagnostic.
