What Is Turing Complete? Infrastructure, Computation, and the New Motor of History
Turing completeness asks whether a system can, in principle, express any computable procedure. But “in principle” hides a physical caveat: unbounded time and memory. Infrastructure—data centers, GPUs, cooling, networks—is the material extension of the Turing tape. It does not change what is computable, but it radically changes what is feasible, viable, and adoptable.
