Byron Reese recently authored a book titled The Fourth Age. I thoroughly enjoyed this fascinating look at history, and the focus on possible futures. In looking at the future, Mr. Reese explores the reasons that experts disagree on the path of these possible futures. He asks: why do Elon Musk, Stephen Hawking, and Bill Gates fear artificial intelligence (AI) and express concern that it may be a threat to humanity’s survival; and yet, why do an equally illustrious group, including Mark Zuckerberg, Andrew Ng, and Pedro Domingos, find this viewpoint so far-fetched as to be hardly even worth a rebuttal? The answer as described by the author lies not in what we know – but what we individually belief. This theme throughout the book is an interesting piece of self-reflection. See how you would answer the questions posed by the author.
