Is artificial intelligence a friend or foe? Or is that a question for Siri?

Every time we ask Siri a question on our iPhones, we're using artificial intelligence, of course, but in what other ways will it infiltrate our lives? AI already goes beyond just Siri or Alexa. Every time you get directions from Google Maps, it's AI that's working out the shortest path from A to B. When you get a film recommendation on Netflix, it's AI that knows about people's preferences and a little too much about you. More than three-quarters of the movies watched on Netflix are those the algorithms choose for us. And we're spending more and more time locked away in digital and virtual realities.
