If you read this article, I think most would understand that it is primarily aimed at other neuroscientists, and only using ML structures an an analogy only, and I think a somewhat useful one to boot. The real point of the article was to propose a general hierarchy for how information flows in the brain, to emphasize the importance of subcortical brain even in higher order cognition, and proposes how simultaneous processing of multiple levels of representation can inform action and thought.

As a developmental neuroscientist, I found the article insightful and thought provoking. Further, it is quite consistent with major hypotheses in psychology, how the hippocampus works (a subcortical structure) and combines information into memories: See fuzzy trace theory [1], for example.

Your dismissive tone is unappreciated, ill-informed, and crass.
