I think you might be the one that's misunderstanding my point. Or the scope of what is being proposed here.
My point is not an objection to other methods being out there but a realistic look at what is being proposed here.
I am also autistic. I have met other autistic people that are high functioning like myself, even in social situations, I have met some that are completely debilitated by noise but are otherwise perfectly capable people, I have met some that are non verbal but can work a computer like a prodigy, and I've met one who will straight up never be able to have even a semi normal life.
Want to know what the common threads between them are? Beyond an ASD diagnosis, not a lot. One person's fixation is another person's trigger, one's need for white noise is another's audial hellscape. AI has difficulty navigating neurotypical behaviour, despite the latter having the most research behind it, never mind neurodiversity. And a mis step can lead to a trigger or a meltdown.
So yeah, there isn't really a one-size-fits-all approach. When bringing it outside to include more than just ASD, you're going to find it hard to find even a one-size-fits-most approach. You kinda need that if you want to make a scalable online service.
