No, this toothbrush doesn't have artificial intelligence

Every year, the marketing arm of the tech industry huddles around a simmering cauldron of PR gumbo and fishes out a single word or phrase that will embody the hope -- and hype -- of the latest generation of gadgets. Previous examples have ranged from the charmingly vague (the "Internet of Things") to the idiotic (the use of "smart" as a catch-all modifier) and the merely hopeful ("3D TVs" were doomed from the start really.) In 2017, though, you should prepare for the over-use of the latest favorite: artificial intelligence. It's clear that AI and machine learning had an impressive 2016. There were advances in features for consumers, like image and speech recognition, but also significant research achievements -- including a milestone victory for machine over man played out via ancient board game Go.
