@icedquinn @hazlin A turing test is just some scifi nonsense about replicating human speech patterns well enough to fool a normie (something that is easy; politicians do it constantly and they're not even a form of slime mold). It has no significance technologically.

I don't think it will ever be feasible to replicate human cognition in a digital computer as we know them. Maybe a 5 kilo monolithic chunk of custom silicon, maybe. Probably not. Consider distance and signal propagation. It's not possible for anything the size of a warehouse to have the same latency as something the size of a melon, just based on the speed of electricity. And a melon isn't realistic. It's a fraction of that that handles cognition; most of your brain processes sensory input and handles biological things. Parallelism is built in to the hardware of your brain; in computers it's largely handled by sequential processors multiplying arrays upon arrays of numbers. Sure, you can add more cores, but not to the same effect as adding more dendrites. Your brain can effectively multiply enormous matrices in O(1).
