While I agree that designing and training a model the size of a human brain from scratch may well be an undertaking too great for any one human or even group of humans, that’s not how humans are created! I’d say the fact that we start life as a single cell with - at maximum - only a couple of gigabytes of information packed in our DNA and yet turn out to have profound intelligence is strong evidence that we might be able to design a system that - through some combination of obscenely efficient simple-ish learning algorithms - might be able to bootstrap its own intelligence in a similar fashion to how humans do. This isn’t necessarily a call for research to study how human embryos turn into thinking, feeling people, but more a loose upper bound on the complexity of the initial size of a model that could become AGI.
