Right, validity is semidecidable, just like the halting problem.
We might never know for certain that any natural law is true, we might never be certain that that oracle actually solves validity. But that doesnt prevent the oracle from working. My point is that its existence is possible, not that we will ever be able to trust it.
Besides, we dont know that the physical laws we work with today are true, but we nevetheless use them for practical purpuses all the time.
I mean if the point is that we know that we know nothing then I’ll agree.
Not my point… and you know it. My point is that even if we consider that proven theorems are known facts, we still dont know if hypercomputers are infeasible. We know, however, that i’ll never write python code that decides Validity because it is not (classically) decidable. But we have no theorems on the impossibility of hypercomputation.
Back to the context though: If the brain can access it, why would AGI be unable to?
