9.2 million parameters per neuron. There an estimated 86 billion neurons in the human brain [0] and 19 billion in the neocortex [1]. That means that, for this strategy to emulate a human brain or neocortex would require 791 quadrillion parameters or 175 quadrillion parameters, respectively. The largest ANN built so far, GPT-3, has 175 billion parameters [2]. We are 6 orders of magnitude from being able to pull it off.
