We haven't emulated brains yet, so we don't know. The OpenWorm project is interesting, but I don't know to what extent they've managed to faithfully recreate an accurate digital version of a nematode worm. I do know they had it driving around a robot.

Thing is that the our brains are only part of the nervous system, which extends throughout the body. So I don't know what happens if you only simulate just the brain part. Seems to me that the rest of the body kind of matters for proper functioning.

I personally believe that while interesting, projects like OpenWorm or humanbrainproject are extremely indirect and unpromising regarding AGI (or even for improving our understanding of human thinking in general).

To me, these are like building an instruction set emulator by scanning a SoC and then cobbling together a SPICE simulation of all the individual transistors-- the wrong level of abstraction and unlikely to EVER give decent performance.

People also like to point out that human neurons are diverse and hard to simulate accurately-- yeah sure, but to me that seems completely irrelevant to AGI, in the very same way that physically exact transistor modelling is irrelevant when implementing emulators.
