Well, some kinds of disability still are a stigma, but here on HN neurodiversity/autism is celebrated as some kind of superpower, basically.

I'm aware. See for instance, VC Arielle Zuckerberg's comment that when deciding which founders to fund she looks for "a little of the rizz and a little of the tis" with "rizz" referring to charisma and "tis" to autism.

One could argue that mythologizing a particular characteristic is itself a form of stigma.
