 There is no reason to believe that we can use the Turing-uncomputable operations just mentioned to compute in the epistemological sense that motivates our interest in computation in the first place—to solve problems, to generate the values of desired functions for desired arguments, to understand certain physical systems, and so on. In other words, the operations in question should not count as computations. Bold Physical CTT, which is threatened by such operations, is not interestingly analogous to Mathematical CTT.
