This seems like an unfair criticism on Gary’s part but I’m not a neuroscientist. I don’t think you have to know everything about the brain to be able to say that neural networks are a “cartoon”/highly simplified mirror of their biological counterparts. Right?https://twitter.com/GaryMarcus/status/1200088188934451200 …

you don't have to know everything, but given we can't answer basic questions, eg -what is computational role of dendrites? -why do synapses have 100s of distinct proteins? -why roughly 1000 cell types? -how is short-term memory neurally realized? we can't be confident of much.
Thanks Gary! I do appreciate you trying to cut through the hype in the field of machine learning- it’s definitely needed.

I'd say the more immediate questions from the other direction are whether tubulins could be qbits and whether epigenetic methylation modulates neuronal response. Gary's questions don't bear as much on the information processing architecture implications, but those two sure do.

I think the short term memory question has some really good answers, e.g., implied by the work at http://haxbylab.dartmouth.edu/publications/NH+17.pdf …
