TODO find/create decent answer.

A basic non-precise intuition is that a good model of reality is that electrons do not "interact with one another directly via the electromagnetic field".
🔗
A better model happens to be the quantum field theory view that the electromagnetic field interacts with the photon field but not directly with itself, and then the photon field interacts with parts of the electromagnetic field further away.
