Now people are looking at a second method for replicating human thought. It's called the neural network. The brain is made up of building blocks called neurons. They're fairly simple, but they have an important feature. Their logical action is adaptive.
Neurons can learn.
Experiments with machines using neural elements are beginning to give some startling results. What one can do is find an answer that's good enough very quickly. Asked to multiply 7 by 6, one might tell you the answer is about 40. It'd take enormous digital-computer capacity to do that precisely. But we don't do it precisely.
