Seems like the consensus taking shape in these comments, the way I understand it anyway, is that the only new thing is pathologising neurodivergence and beginning to actually accept such people into society. Treating it as something new or out of control is merely a reaction to new norms.

A lot of kids are not neurodivergent, still. But there are enough that school budgets for special needs in many or most places are very badly under-provisioned. I worry that if schools are not going to get massively higher funding, they will be faced with either under-serving neurodivergent kids like they used to, or fundamentally rethinking some things.
