By definition nothing will ever compute an uncomputable function. You’re only stating a trivial truth that by itself fails to refute the conjecture that we live in a reality that has behaviors that cannot be accurately described by computable functions and that we are forever stuck with merely approximate computable models.

In fact, so far we’re not able to completely computationally predict any behavior of reality. Even the marvelous theory of quantum electrodynamics is only shown to be accurate to, last I knew, about a dozen places.

Due to an unfortunately widespread misunderstanding of the Church-Turing thesis, far too many otherwise intelligent persons with some CS knowledge are completely blinkered to the possibility that the universe could have behaviors that are real, but not describable with computable functions beyond approximately. The practicing laboratory scientists I’ve spoken with don’t generally share that defect since they’re used to everything being approximate.
