'GR is not only a formalism': a physics spat over general relativity's truth value

Science communicator fkasummer forcefully pushed back on the claim that general relativity is 'only a formalism': "GR is a proper theory. It has truth value. It's always these idiots with absolute certainty."

A philosophy-of-physics spat, tangential to AI.
