You could try looking at existing animal neural counts: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_animals_by_number_of_neurons" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_animals_by_number_of_n...</a> Doublings or 20xing get you a long way: a 1&#x2F;20x cerebral cortex neural count decrease takes you from human to... horse. I like horses a lot, but there&#x27;s clearly a very wide gulf in capabilities, and I don&#x27;t like the thought of ever encountering someone who is to us as we are to horses.
