In worlds where brains are ultra-efficient, AGI necessarily becomes neuromorphic or brain-like, as brains are then simply what economically efficient intelligence looks like in practice, as constrained by physics.
Not necessarily. There could be multiple ultra-efficient cognitive architectures, and the brain would represent one of them.
You are correct. I should reword that a bit. I do think the brain-like compute basin is wide and likely convergent, but it’s harder to show that it’s necessarily a single unique basin; there could be other disjoint regions of high efficiency in architecture space.
