 To fully assess Modest Physical CTT, we should consider whether it is possible to build a machine that, like an ordinary digital computer, can be used by human observers, but, unlike an ordinary digital computer, generates the values of functions that are Turing-uncomputable. In recent years, several designs for hypercomputation have been proposed. Hypercomputation is the computation of Turing-uncomputable functions. If hypercomputation turned out to be physically possible, it would refute Modest Physical CTT.
