Don't get too bogged down on the modern "autism" term. It's almost certainly going to change as we learn more about it.

Right now autism and neurodivergent cover huge swaths of behaviors/traits. This is especially true in the "social arena".

Just like back in the day when every kid that bounced their leg got an ADHD diagnosis. Now we know ADHD presents in a ton of ways and is usually present with other personality traits.
