Autistic People. So, new Research. Different social skills, not broken ones.

"In essence, what we are demonstrating for the first time is that autistic people's social behaviour includes effective communication and effective social interaction, in direct contradiction of the diagnostic criteria for autism. We have, for the first time, uncovered empirical evidence that there is a form of social intelligence that is specific to autistic people."
In other words, different social skills, not broken ones. We have our own social signalling and can co-operate and interact effectively....with each other. Likewise, non-autistic people can generally co-operate and interact effectively...with each other. But put one of each group together, and they both tend to misunderstand one another. They don't feel rapport with one another, that sense that you just 'click' with someone and understand them.
This isn't a new theory, of course. Dr Damian Milton has been discussing Double Empathy theory for a while now. https://kar.kent.ac.uk/62639/1/Double%20empathy%20problem.pdf
