Why not? For a hypothetical example - if we assume that simulating a human is AGI, and we have some hypothetical space-age magic tech bruteforce the problem by simulating every neuron and connection in the brain... why would being "embodied" factor into this?
Because I think intelligence formed in human beings is connected directly to embodiment and not some kind of abstraction that can be simulated. My guess is that the best AI developments will ultimately come from mimicking the processes of how humans learn from their environment, and not from merely simulating (or trying to simulate, as I don’t really buy the positivist approach) human brains.
Absolutely. The physical world is the input that creates the feedback loop for learning.
I would propose a definition of AGI. "A model capable of effecting the physical world through speech or physical action in a manner indistinguishable from a human."
