OTOH, "computability" could be intended in the (Wolframian?) sense
that there are no shortcuts. A given problem is uncomputable if it is
not "reducible", so you have to run the process and see where it
leads. This however tells us nothing about the fact that a
functionally equivalent process can be implemented on a different
platform. For instance, you can run a cellular automaton with pencil
and paper or with a PC.
