The model I am using is the conventional understanding of physics. What model are you using?

> language meaning is not immutable physics.

Our understanding of physics is not complete, so why would our model of it be final? No one is saying it is.

Everything we currently know about physics, all the experiments we've conducted, suggests the physical church turing thesis is true.

If you want to claim that the last x% of our missing knowledge will overturn everything and reality is in fact not computable, you are free to do so, and this may well even be true.

But so far the evidence is not in your favor and you'd do well to acknowledge that.
