@Energetic_Nova @pathfinder @autistics Important points to keep in mind:
(1) The existing concept of #disability is problematic, in that it links the amount of help someone needs with their potential for achievement. But someone who has very high potential can still need a LOT of help to realize that potential. The distinction between "severe" and "non-severe" #autism overlooks the possibility that one and the same person can have very high support needs AND very high potential.
(2) When someone's potential IS limited, it isn't generally clear exactly WHAT is limiting it. My hypothesis is that autism itself NEVER severely limits potential, although it may impose very high support needs. But autism can commonly coexist with other types of intellectual disabilities that DO limit potential. Severe intellectual DISABILITY, yes; severe AUTISM, no.
(3) Caregivers of #autistics — and, even more so, mental health professionals evaluating autistics — have a track record of grossly underestimating their potential. Even #TempleGrandin's parents were once told by a doctor that they might as well commit her to an institution and forget about her. (Fortunately, her parents didn't accept that.)
