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 …

Not here to fight, but may I ask how symbol-manipulation is implemented in the brain (if not by a network of interconnected neurons)?
Don't know the answer to this, but (a) I made some suggestions in The Algebraic Mind, chapter 3, and (b) I also don't know how short-term memory (of the write-once, then immediately retrieve variety) is implemented in the brain, but that doesn't make me doubt its existence.

I never said I doubt our capability to do symbol manipulations. I am just asking for suggestions as to how it may be implemented, if not by a set of interconnected neurons.
