Humans can certainly replicate TMs. It's uncertain whether a TM can replicate a human. If the Universe is a simulation running on a TM, then humans are replicable and therefore Hard AI is possible on a Von Neumann architecture, which would be an exciting discovery.
- nardi 13y agoFrom the perspective of computing things, humans are Turing Machines, because a Turing Machine can compute anything that is computable.
- redthrowaway 13y agoThat's like saying from the perspective of arithmetic we're abaci because we can both do sums. Again, whether or not human beings can model a TM is a boring and silly question. The interesting question, and one that remains not just unsolved but stubbornly resistant to progress towards a solution, is whether a TM can model a human. It's far from certain that conscious is computable, and it's getting further with each plate of spaghetti we throw at the teflon wall that is Hard AI.
