[2] "I’m stitching across a lot of different research, and I want to be clear many aspects of this system are not yet fully worked out.
But what we do know points to a system that works with different physical and algorithmic priors, and the dynamics are sharply distinct from current digital computers." Hmm, I wonder if "we" figured that stuff out from individual and especially collaborative efforts combining abstractions and more theoretical approaches with expertise in biology, not to mention EE, biophysics, physics, and whatever else other fields that don't know about his favorite molecule and thus can be ignored if not shit on?
Where the hell did you get that from?! I mentioned the hash table / embedding space analogy precisely ONCE, in my initial post, and, just to try to avoid people like yourself being triggered by it, I even included "obviously the brain is not a computer".
But you still got triggered by it, still did the dumb take of "a brain is not a computer" (no shit - I just said that), then spent your entire energy on fighting your own strawmen and not once even responding to my actual suggestion.
Now, finally, you are asking "what is a sparse embedding"! Maybe next time don't bother responding to something if you don't even understand what is being talked about.
