The rest is just a lot of nit picking and what not for very specific ways to do AGI, very specific definitions of what AGI is, is not, should be, should not be. Etc. Just a lot of people shouting "you're wrong!" at each other for very narrow definitions of what it means to be right. I think that's fundamentally boring.
What it boils down to me is that by figuring out how our own intelligence works, we might stumble upon a path to AGI. And it's not a given that that would be the only path either. At least there appear to be several independently evolved species that exhibit some signs of being intelligent (other than ourselves).
I can write a useless and poorly-argued paper about P != NP (or P = MP), and it would be twaddle regardless of whether or not I guessed the equality / inequality correctly by pure chance.
