This claim, which has gotten a ton of traction, rests on a pretty obvious error. The claim that all math is produced by physical objects should be read as the claim that all *representations* of mathematics are produced by physical objects.

Yes but that is a claim about the computer simulation, not a claim about the content of the computer simulation. A simulation of Superman is not Superman.

The limits of my or a computer's capacity to represent mathematics is not necessarily evidence for the limits of mathematics.
