A revolution of intelligent machines, from self-driving cars to smart digital assistants, is now remaking our world, just as the Industrial Revolution remade the world of the 19th century. AI is used to diagnose and treat cancer, detect fraud, save energy, and make new discoveries. AI is not some science-fiction droid from the future. It's right here, right now, and it's changing our lives at lightning-fast speed. Many of these changes offer great promise, including freedom from drudgery, safer workplaces, better health care, and fewer language barriers. But others elicit worry--whether about jobs, data privacy, or the prospect of machines making biased decisions with no accountability. In AIQ, authors Nick Polson and James Scott, both experts in the field, show us how to make sense of these accelerating trends.
