How to Explain Neural Networks to Lay People?

The brain is composed of norons, you know, in ourselves, and they are connected to each other. We have something like 86 billion of them a most people. And the way we learn that the strength of the connections between those nerons change,. And so we do the same winh normal nets. We simulate e large networks of those nerons. And the learning procedure changes the strength of those connections. Those are just numbers, right? What each of those norons is doing is an incredibly simple operation. I bisly computes a a weighted sum of its inputs, and then if the waited sum is below the threshold, it says quiet. If it's above the threshold,
