Artificial intelligence is changing our lives in ways we need to understand. Algorithms govern how we find information, how we learn, how we move, how we buy, what we buy, how we stay healthy, how we meet, whom we meet, how we are treated and what we are treated with. Marketing, analytics, diagnostics, manufacturing, driving, searching, speaking, seeing, hearing are all being disrupted and reshaped by machines that learn. Algorithms that can operate at the speed and scale that data is now generated are now making, what once was impossible, a practical reality.
