I've been thinking about the neural networks we are creating. They are fractal of course. We are rewiring our brains -changing our internal neural nets- while at the same time, at a different scale, we are building social neural nets with our social networking tools.
Robert Wright wrote a delightful piece about the social brain called Building One Big Brain in the Times last summer.
Vernor Vinge writes beautifully about the singularity in a number of his novels.
Intelligence is a network phenomenon. We are growing and complexifying our social neural network at an astonishing pace. Maybe, linked together, we will become homo sapiens.
