I like the questions, esp. this one: > If new cognition is needed, is it possible from the brain scale-up I mentioned before? Or is it like an aleph0 to aleph1 transition? I suspect there is a Turing completeness to cognition - in that there are some base laws which makes access to all math possible. There is indirect evidence from multiple studies of ML models and animal intelligence pointing in the direction of "scaling up is good for intelligence, if your system isn't limited by global connectivity too much".
