How AI came to rule our lives over the last decade

San Francisco (CNN Business)In 2010, artificial intelligence was more likely to pop up in dystopian science-fiction movies than in everyday life. And it certainly wasn't something people worried might take over their jobs in the near future. A lot has changed since then. AI is now used for everything from helping you take better smartphone photos and analyzing your personality in job interviews to letting you buy a sandwich without paying a cashier. It's also becoming increasingly common -- and controversial -- when used for surveillance, such as facial-recognition software, and for spreading misinformation, as with deepfake videos that purport to show a person doing or saying something they didn't.
