How artificial intelligence is reshaping our lives

It's Saturday night and you've just finished watching the last episode of a Swedish crime drama that you somehow stumbled upon, although you can't quite remember how. It's late and probably time for bed, but--without prompting--your Netflix screen fills with promotional shots for more shows. There's one about a female detective in Denmark and another about a British inspector who weaves between both sides of the law. It's a familiar scenario to any Netflix watcher--when the service seems to magically suggest programs that fit your latest pop-culture craze. These days, the computer algorithms that allow Netflix or Amazon to make purchasing suggestions are a normal part of life.
