You’ve probably heard of artificial intelligence by now. It’s the technology powering Siri, driverless cars, and that creepy Facebook feature that automatically tags your friends when you upload photos. But what is AI, why are people talking about it now, and what will how to invest in artificial intelligence stocks mean for your everyday life? AIĀ is what people call computer programs that try to replicate how the human brain operates.

For a human, this is fairly easy, but a computer has a hard timeĀ figuring it out. AI systems are unique because they are set up like human brains.
