Of course, every so-called unification theory promises to bridge the gap between quantum physics and classical physics. This one is no different in that regard.
But what separates constructor theory is that it’s imagined as a direct technological paradigm. Proponents submit that a hypothetical “universal computer” is starting look more and more possible as we push the limits of quantum computing.
Eventually it’s possible we could scale quantum machines to a level of usefulness where the ability to run compute tasks is more dependent on the robustness of the algorithms running it than the amount of power we can muster.
When this happens, some scientists believe self-generating artificial intelligence paradigms running on machines featuring billions or trillions of qubits in action could sufficiently cross over into “universal computing” territory and be capable of running any and all possible compute tasks.
