"Total Recall: How the E-Memory Revolution Will Change Everything" is a book written by Gordon Bell and Jim Gemmell, with a foreword by Bill Gates. It explores the concept of digitally recording and storing every aspect of our lives, creating an "e-memory" that can be accessed and searched. The book draws on the authors' experiences with the MyLifeBits project at Microsoft Research, where they experimented with recording and cataloging vast amounts of personal data. The authors argue that this "e-memory revolution" will fundamentally change how we think about memory, history, and even our own identities. The book also provides practical advice on how to start taking advantage of this technology, including navigating privacy concerns and choosing the right tools.
