Profound autism, is it real, or is it just intellectual disability with certain autistic features? People with intellectual disability, who are also talkative and extrovert and keen on social interaction are not called 'profoundly neurotypical'.
This sort of thing, like assignment of species in human evolution, tends to switch between 'lumpers' and 'splitters'. The 'spectrum' saw lumpers in the ascendant, perhaps the pendulum is swinging the other way?
