I think a long ways away, if I understand this article about the difficulties involved in accurately modeling even a single biological neuron: https://www.quantamagazine.org/how-computationally-complex-is-a-single-neuron-20210902/ https://www.quantamagazine.org/how-computationally-complex-i... > "If each biological neuron is like a five-layer artificial neural network, then perhaps an image classification network with 50 layers is equivalent to 10 real neurons in a biological network." The complexity explodes quickly because each biological neuron's behavior is modulated by a large number of biochemical neurotransmitters, on top of all the dendritic connections (up to 15,000 each, apparently).
