Predictions are a mug’s game. If they come true, you likely didn’t push your thinking hard enough. If they don’t come true, you risk looking like an idiot.

The video above takes a quick spin through just some of them, with thoughts from tech pioneers including Nicholas Negroponte, Rodney Brooks, Jeff Han and Pattie Maes.
