      If you're interested just read any basic cogsci introductory book. The problem is that computer science is integral but sadly many don't

      have enough background in it to appreciate eg P=?NP, Gödel's I completeness, etc., and how they relate to cognition.

      The mainstream philosophy of cognitive science sadly got some stuff very wrong, like that theoretically blind ML would create the best model

      Interesting, I'm curious where you see that idea expressed in mainstream cog sci.

      They thought some theory would account for cognition. But the best models are atheoretical currently.

      Deep neural nets built using brute force, not due to understanding how they work. That's not theoretically driven.

      I think there's plenty of theory there, about units of processing, directionality of information flow, connectivity.

      The people who build them say they have no idea. I think the high level theory is lacking IMHO.

          Also no theory attached to the brain and yet the model captures human vision computations.

          But they don't really have "no idea". That's just a turn of phrase. They do understand basic principles of CNN, just not how it all fits >

          These people aren't in cogsci. But I have a feeling we use understand and theory differently.

          Some of the best (in terms of classification accuracy) models are just "add more layers". Eventually this heuristic might not help. Why?

          That lack of understanding doesn't make then atheoretical, IMO. Noone understands all implications of their own models.
