If you have read Sapiens, you will be inclined to read Homo Deus (Which BTW is not a fictional story about a guy named Deus who is too afraid to explore his sexuality). If you have read both of these books, you would be literally compelled to pick up this one. The pace at which things around us are changing is mindbogglingly high but unfortunately the thought process and collective consciousness is terribly jet lagged. And this genius man in the present book picks up 21 topics which we should deeply ponder on before embarking upon forthcoming spiritual and philosophical voyages. Each topic contains intriguing debates spanning across eons.
For instance, he talks about the responsibility which rests on the shoulders of story tellers these days, particularly those engaged in science fiction. The perception of future is more shaped by these science fiction movies and TV series rather than the actual status of research itself. What if Neo wasn't really out of the matrix at the end, what if it was another matrix. Matrix within a Matrix. What is we all are truly inside the same one and Neo is just a self-affirming dream figure. Many more such propositions in the book. And by design, the last chapter of this book is titled Meditation. It's about time we make effort to understand our own minds, before the algorithms take over. Pick it up and read, period.
