The beyond-Turing universe

 

The “conventional” view

“Every finitely-realizable physical system can be simulated efficiently and to an arbitrary degree of approximation by a universal model (quantum) computing machine operating by finite means.”
 

leaves out the possibility of beyond-Turing computing:

Every realizable physical system can be simulated efficiently and to an arbitrary degree of approximation by a hyper-/quantum-/biomolecular-computing (HQB) machine.
