Harari offers refreshing clarity and insights in all his books, but in this one he really commits to some foundational ideas and arguments in a way he hasn't in previous works. The nature of information and truth are at the heart of the culture tech wars we are embroiled in, and this is the only analysis I've encountered that really grapples with that. I suspect the resulting insights are on the right track, and the lack of easy answers is a recognition of the volatility and complexity of our times.
