AI Essentials

Cut through the hype and the headlines. In this guide you will learn what people actually mean by "AI" today, how the modern kind works in plain terms, and why it can be so helpful and occasionally so confidently wrong.

"AI" covers a lot of ground, so this guide sorts it out. You will learn the difference between the narrow AI we have today and the general AI of science fiction, meet the everyday tools you are likely to use, and see why some AI creates new things while other AI predicts.
