That sounds like one of my pet ideas I was calling 'physical autism'.
I am convinced that we are surrounded by two kinds of autistic behavior but are conditioned to mostly notice one of them.
Social autism (the normal kind we're familiar with) is usually evident in person. It's a spectrum from debilitating to barely evident. Some people I've talked to online have been autistic and I'd never know it just by conversing. I generally prefer it this way because it removes any prejudgements. I liked the Net better before social networks made people's photos, names and assorted history available, I feel like you got to know people more intimately.
The kind of autism we mostly don't notice is physical. There are people who are experts at social interaction, but who genuinely cannot understand the physical world, they never think about it. Their world is filled with people and nothing but people. These are the people who are blinded by the sun.
All of the world's accumulated knowledge is utterly lost on them and they have no sense of an objective reality outside of the realm of relationships. In its own way, this is a disability because they can never be more than their network of connections.
Most people know people like this but think that those people choose not to be interested in X,Y,Z. I suggest that maybe they literally cannot fathom those things, or at least have a severe hindrance in their path to doing so, similar to the social autism spectrum.
