I don't think ASD has an "essence", because it isn't a single condition, it is a large number of distinct conditions, with distinct causes–grouping them all together as "ASD" is a sign of how poorly we understand them. As we improve our understanding of those distinct underlying conditions and causes, I think ASD as a diagnosis is going to disappear, to be replaced with multiple more specific diagnoses.
