Of course, we can spot several underlying metaphysical assumptions in the general claims that OmegaZero2003 and I have been sharing: 1) Computation is universal! 2) All mechanistic notions in all cultures are computational! 3) C-T thesis is correct for all living beings! etc. etc. Disregarding the general claims for the moment, let us come up with a more concrete question. Will not these aliens build something like a cola vending machine? And when they construct a theory of making machines which have similar operational qualities, will not they have invented computer science? I think this is first and foremost a question in philosophy of mathematics. How universal is mathematics? Is discovery of a set theory unavoidable much like the discovery of gravitation is? Possibly, but not easily put into a philosophical argument I suspect. I believe that any civilization that will embark on number theory or set theory will also invent computer science for the above mentioned empirical reasons. The adaptation of computer science allows one to build a powerful predictive apparatus about a wide array of machines with equivalent mechanical capability. That is exactly why FSM is a useful concept which is not limited to describing the design of cola vending machines, but deals with a universe of such machines and abstract relations concerning these constructions!
