I agree with the thrust of this comment, which I read as saying something like “our current physics is not sufficient to explain, predict, and control all macroscopic phenomena”. However, this is a point which Sean Carroll would agree with. From the paper under discussion (p.2): “This is not to claim that physics is nearly finished and that we are close to obtaining a Theory of Everything, but just that one particular level in one limited regime is now understood.”
The claim he is making, then, is totally consistent with the need to find further approximations and abstractions to model macroscopic phenomena. His point is that none of that will dictate modifications to the core theory (effective quantum field theory) when applied to “everyday” phenomena which occur in regions of the universe which we currently interact with (because the boundary conditions of this region of the universe are compatible with EQFT). Another way to put this is that Carroll claims no possible experiment can be conducted within the “everyday regime” which will falsify the core theory. Do you still disagree?
For the record, this is just to clarify what Carroll’s claim is. I totally agree that that none of this is relevant to overcoming the limitations of formal verification, which very clearly depend on many abstractions and approximations and will continue to do so for the foreseeable future.
