In the Terminator movies, the trouble begins when the computing colossus Skynet becomes self-aware. This year may have witnessed the arrival of baby Skynet. IBM researchers announced the creation of the first artificial device that truly mimics the operation of the neurons in our brains -- artificial nanoscale stochastic phase-change neurons. I don’t pretend to know how it works, but it uses materials scalable down to billionths of a meter, consumes almost no energy, and is capable of unsupervised learning at speeds far faster than any computer. Here’s what I do know: there’s no fate but what we make for ourselves.
