As physicist Heinz Pagels has said: “The difference between a real neuron and the model neurons . . . is like the difference between a human hand and a pair of pliers.” But the fact that a simple neural network can speak at all is remarkable, indicating that perhaps human abilities can be simulated by electronics. . . . Which is the most accurate summary of Kaku’s argument?
