We already do treat it as the latter. The medical definition of autism is basically just any neurodevelopmental disorder that isn’t ADHD.
"we do, autism is everything that isn't ADHD"
...what? I must be stroking out, but I have no idea what point you're making here...?
That's not really true. Not to mention the very TFA, and the research that led to papers like it, is based on the opposite.
But that's it. It helps with research, that's it. You still need doctors, typically multiple different doctors of different specialties, if you want correct treatment. The AI is a good starting point, so you can start asking your doctor the right questions, but it's never the ending point. At least, in my opinion. I'm sure it depends on the condition, and how much it follows a template.
