As Rolf Landauer said "Computation is physical",
Yes, Landauer is a major proponents of that idea. If that is true,
then computationalism is false.
all computations must use energy and generate heat. And what's the
difference between a physical process and a non-physical process
anyway?
With comp, a physical process is the result of the first person
(plural) indeterminacy beaing on all computations. It involves Qubit,
and can exploit Fourier transform on infinities of result in alternate
computations. A non physical process would be defined by number
relations involving only finite and local informations.
