Yeah thanks, me too. So I'm wondering what point 22 is getting at. How could that even be possible?

Biology can use discrete methods; we have discrete neurons (and other cells), discrete chemical species like ATP, discrete amino acids, discrete genes made of discrete nucleotides, etc.

Fur sure. But I don't get how that leads to an expectation that our biology is computing and utilizing derivatives in a computational graph.

Point 22 seems to imply that the other finds it notable that that isn't happening.
