We do have some pretty sophisticated models of neurons, and there are persistent theories (2015 was earliest I found in a quick search) that brains use some quantum physics, in particular Quantum Entanglement, to operate.

In which case, hardware has a very long way to go before we can do that at scale.

Modeling neurons and simulating them with AI are very different things. And, as you say, we still know very little about neurons and the nervous system and the brain itself. How, then, could we even attempt to train an AI to work accurately?
