AI is everywhere but, in almost all cases, they are located outside or at least on your body. Smart speakers are left inside rooms and smartwatches stay on your wrist. But a new smart device that’s available exclusively in Apple Stores applies AI inside your body. Don’t worry, it’s not invasive, at least not in the “skin-piercing” sense. This new Colgate smart toothbrush uses a bit of artificial intelligence and crowdsourcing to analyze your mouth and your brushing method and tell you how to brush your teeth better.
