@marymessall @NicelyManifest @autistics Yes, I also believe it is an evolutionary advantage, for the group as a whole, to have the diverse individuals in it.
My best guess as to what valuable, and even indispensable contribution Autistics contribute is this: they aren't beholden to status/emotional approval from mentors, as some sort of motivating reward (Asperger originally observed this, as noted in the book "Neurotribes").
The narcissists of the world can lead their flying monkeys (an even possibly entire populations by extension), to ruin - possibly large numbers of them, by dangling motivations of status and money in front of neurotypicals, like a carrot on a stick.
Just look at what's happening in the AI world, for example (sorry for the X link, but it's a potent, recent example):

It's through such emotional and status-motivated - not really rationally-motivated - puppet strings, that narcissists can gain so much leverage over everyone, like a skilled puppeteer.
IMHO, The Autistic are a necessary evolutionary hedge against this. They aren't as beholden to these emotional puppet strings - this carrot and stick motivation for status - that neurotypicals are. Autistics offer a possible course correction (albeit, an emotionally uncomfortable/painful one to hear), where the neurotypicals can't really do it themselves - the status/money is too attractive, as opposed to "doing the right thing"
