My focus was on the more philosophical/impractical side, and the computers we can actually build in principle, assuming the laws of physics are unchangable and we are basically correct, we can’t even build Universal Turing Machines/Turing Complete systems, but just linear bounded automatons, due to the holographic principle.
Also, the entire hierarchy can be solved simply by allowing non-uniform computational models, which is yet another benefit of non-uniform computational models.
