      Great! New thread then: What are the ways in which people in the neural net community think that today's ANN's are NOT perfect models of the brain? Where do you want to dig deeper, and why?https://twitter.com/timkietzmann/status/1200159447651438592 …

      100% this! I know of nobody in the community who would say "today's ANNs are perfect models of the brain, let's not dig deeper".

      Not a neuroscientist, but my own opinion is that weighted gating, compositionality, and learning are the foundations of bio neural nets, and all other phenomena that we care about are built on these blocks. Traditional computers only do the first, but DL can do all three.

      I personally see no reason a priori why the specific mechanism of these three functions (kludged together by incremental evolutionary silliness) would matter to the emergent phenomena, so arguments like "neurons don't back-propagation" seem a bit spurious to me.

      (i haven’t endorsed that argument, though people on my side sometimes do.)

          Wasn't attributing to you, just trying to clarify my position.
