>This is all true but it's not actionable. By that I mean, it's philosophically correct but not practically applicable. Yes, mathematical theories are merely a model of actual reality. But a model that produces accurate predictions is useful--even if we know it is not a complete model.
That's true, but that's not all the above says though.
It also says something else that _is_ actionable: don't just trust (or defend) a physics theory because it says it uses math or because it got its math right.
It could still be not just non corresponding with "real reality", but even get its predictions wrong.
What people trust in or defend wrt/ physics theories isn't really relevant to the science, all it does is setup some social direction -- Which one needs regardless of whether they have a correct theory or not.
You've got to fund somebody. So you fund the people with the math that looks good. Objecting to that is basically asking for unrestrained corruption. Crackpots certainly can't be relied upon to identify themselves.
