On a quick search, I found this Forbes article and this article from Autism Housing Network. The Autism Housing Network appears to be a treasure trove of resources about this very interesting idea in general.

However, I'm honestly still a bit skeptical to the movement for autistic intentional communities as it stands. I found out about this movement earlier today, when I correctly figured while writing an essay that somebody else had probably already come up with that exact idea. However, while the extant communities are improving people's lives, they don't really seem like the sort of radically by-of-and-for-us type of neurodiverse communes that I was imagining while writing my essay. Rather, these extant communities feel like a sort of more status-quo-y liberal housing development with a neurodiverse flavor.

In my essay I had even written about all sorts of pipe dreams of cybernetics and e-democracy to connect different intentional communities together, but I guess that's all it is: pipe dreams.
