What Is Artificial Intelligence, and How Does It Affect Your Daily Life?

Artificial intelligence, better known as AI, sounds like something out of a science-fiction movie. It brings to mind self-aware computers and human-like robots that walk among us. And while those things are part of the overarching artificial intelligence definition and may exist in the future, AI is already a big part of our everyday lives. So, what is artificial intelligence, exactly? It's complicated, but every time you use Siri or Alexa, you're using AI, and that's just the beginning of its practical applications. "The main benefit of AI is that it can bridge the gap between humans and technology," says AI researcher Robb Wilson.
