But a brain sim wouldn't be an artificial lung, would it? Much like an artificial heart wouldn't tell you about the state of the valves because it's an entirely different design that satisfies the same purpose. A simulation tries to do what the original does though. For instance a GameBoy emulator actually runs code in the way the original device did, right? Perhaps the test here is a bit like the Turing test. Could you tell whether the artificial device was being used, or the actual thing, apart from examining the device, of course: - An artificial lung doesn't make people breathe in quite the same way I suspect. - An artificial brain would give answers a bit like what ChatGPT can already do.
