      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 …

      Jason Antic added,

      Gary Marcus @GaryMarcus
      astonished that anyone knowledgeable could claim that neural nets are (obviously) an “abstraction of neural processing” when we don’t yet know how brains work. if you don’t know how Y works you can’t really speak with certainty about whether X is an abstraction of Y. Period. https://twitter.com/tyrell_turing/status/1200072223299657728 …

      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 …

      given that a voxel contains 50k+ neurons, i think the descriptions there are likely to be too coarse.
