Not OP, but the premise is just too naive. He's coming from a compsci deep learning angle and thus arrives at a completely flawed model for how neurons interact and "compute".
Not that we have a model that even explains this theoretically yet, but it makes no real sense to talk of Brain FLOPs in the way he does.
It's borderline cringeworthy that this is upvoted so high.
The dismissal is cringeworthy, the human cortex only consumes 0.17 watts https://www.biorxiv.org/content/10.1101/2020.04.23.057927v1....
Which put a very low upper limit to the number of simultaneous neurons that can be activated.
Considering it as FLOPs or not is irrelevant to this fundamental limitation and that is the point you are all ridiculously missing
The amount of complexity casually thrown away. The premises and the conclusions. The fact that this is on the front page.
That we are discussing it; the only reason this blurp is here on top of hn is the author and his cult following.
