Why is success deceptive and what does that have to do with robot brains, and more important, our current paradigm of innovation? Because nobody innovates in a vacuum, we can look at innovation as a network phenomenon. Network activity can take things that seem distant or unrelated and prove they belong together. Like dropping out of college to tinker in a garage and later running a billion-dollar company. Or vacuum tubes and computation.  

“Nature has an evolutionary algorithm, and it depends on emergence.”

  This is precisely what Kenneth Stanley and Joel Lehman, artificial intelligence (AI) researchers and authors of the book Why Greatness Cannot Be Planned, wanted to understand when they invented the Novelty Search algorithm. If robots can stumble upon the right answer more effectively than working a plan, maybe there’s a lesson in there for ambitious human beings. Nature has an evolutionary algorithm, and it depends on emergence. Nature is telling us that wild goose chases can be good or bad, depending on which scale you’re zoomed in on. It seeks novelty and will adapt and assimilate nearly everything in its path. Path dependence (time’s arrow), prevents us from mapping the great open search space that is the future. We only ge...

It’s not the midges that were the problem, says Andrea Cavagna, but the kids. You’d think his efforts to record the movements of midge swarms in the public parks of Rome near sunset would be fraught with risks of being eaten alive by the little beasts — but these were a non-biting variety. Keeping away the children who gathered to watch what these folks were up to with their video cameras, generators and thickets of cabling was another matter. That, and the problem of finding a parking space in central Rome. It’s not easy, he realised, for a physicist to turn field biologist. The reason why Cavagna, based at Sapienza University in Rome, and his colleagues went midge-hunting sounds strange, perhaps even bizarre. The researchers wanted to know if midges behave like magnets. More specifically, if they act like magnets close to the point where heat flips them between a magnetic and non-magnetic state: a so-called critical phase transition.  

“It’s a delicate balance: you need stability, but also responsiveness.”
