I think the underlying error - is the assumption that everyones model is going to be equal when looking on the world, as a world of objects. That holds up- for a surprisingly small number of objects we all interact with.

Then it breaks down- depending on how deep your abstraction level goes (A car has 4 tires. 4 tires are made of: xyz). It also breaks down, with the abstraction in the real world above the modeler. Some think in organization, some in physics, some in tribalist constructs, some imagine a god object above them some don't. It was communicated as a tool using "shared" state as a communication helper.

But we do not share as much state as expected.
