Well, you can model every single thing in the entire universe with just NAND too as that's the lowest level primitive. We are searching for higher level analog primitives that can be used to construct these networks. I'm thinking the current primitive of the neuron in ML may be a bit flawed as a foundational primitive but I certainly don't think we need to model the complexities of a biological neuron.
