The Fourth Age

  • The most distinctive characteristic of the last century or so might seem to be the enormous amount of change that has occurred. Dozens, if not hundreds, of advances are said to have revolutionized our lives. The list includes automobiles, air travel, television, the personal computer, the Internet, and cell phones. Change is everywhere. We have harnessed the atom, flown into space, invented antibiotics, eliminated smallpox, and sequenced the genome.

    But within the context of the overall arc of human history, little has changed in the past five thousand years. Just like the people who lived five millennia ago, we too have moms, dads, kids, schools, governments, religions, war, peace. We still celebrate births and mourn death. Forever with us, universal to all cultures of humanity, are sports, weddings, dancing, jewelry, tattoos, fashion, gossip, social hierarchy, fear, love, joy, happiness, and ecstasy. Looked at through this lens, humanity really hasn’t changed much in all that time. We still go to work in the morning;, only the way we get there has changed. In ancient Assyria, toddlers pulled around small wooden horsey toys on wheels with a string. In classical Greece, boys played tug-of-war. Ancient Egypt was renowned for its cosmetics, and millennia ago, Persians celebrated birthdays in much the same way as we do, with parties, presents, and special desserts.

    No, the remarkable thing about our time is not the change we have seen; rather, it is the change we haven’t seen. The really amazing thing is how similar we are to our forebears. In ancient Rome, gladiators were paid celebrity spokesmen who recited product plugs just before the competition: “That’s why I use Antinius’s swords. You won’t find a better sword at any price.” And just like in our times, there were people willing to perform dramatically destructive acts just for the fame that doing so brought about, as was said to have happened on July 21, 356 BC, when an arsonist named Herostratus burned down the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World, simply for the everlasting fame it would bring him. In response, a law was passed that made saying his name a crime, but clearly Herostratus got his wish.

    If you went to visit a friend in antiquity, you might have seen mounted on the door a brass lion’s head with a ring in its mouth to be used to announce your arrival. If you attended a wedding five thousand years ago, you likely would have joined the wedding party as they wished good fortune on the new couple by throwing rice. Today, when we read that archaeologists have dug up ancient lead slingshot bullets each engraved with the word “catch,” we still get the joke.

    These people of antiquity were just like us. To really appreciate the unchanging nature of humans, one need look no farther than a book called Characters written by a Greek named Theophrastus 2,300 years ago. He satirized humanity itself, and sorted us all by type, such as the Flatterer, the Boor, the Chatty Man, and so forth. If you know someone who takes photos of his meals and posts them online, you might see him in the person Theophrastus calls the Garrulous Man, who “begins with a eulogy of his wife, relates the dream he had the night before, tells dish by dish what he had for supper,” and concludes that “we are by no means the men we were” in times past. Theophrastus then goes on to describe the Stupid Man, who “when he goes to the play, is left at the end fast asleep in an empty house. . . . After a hearty supper he has to get up in the night, returns only half awake, misses the right door, and is bitten by his neighbor’s dog.”

    No, against the backdrop of history, our time has seen very little change. In fact, I maintain that things have only really changed three times in human history. Each time was due to technology. Not just a single technology, but groups of interrelated technologies that changed us in fundamental and permanent, even biological, ways. That’s it. Just three big changes so far.

    This book is about the fourth one.

    The Fourth Age: an exceptional read . . . in a class of its own Having read scores of books, papers, and articles on AI, Automation, and Robotics, I’ve enjoyed my fair share of great reads. But The Fourth Age is truly exceptional. It is the only book that exhaustively—and so fairly—covers every single question, concern, upside, and downside of these breakthrough technologies. And all the while, through every chapter, maintains its objectivity. Throughout the book, the author provides readers with his own reasoning and rationale along with those from an abundance of scientists, theorists, technologists, business leaders, and futurists that stand on every side (pro and con!) of each and every issue. And whether the reader is steeped in these technologies, or altogether new to them, this book will be your friend—because it walks you through these technologies in easy-to-grasp ways. I must admit, as a tech enthusiast, when I first bought the book, I thought I would only review a few chapters… but after a few chapters, I was so hooked that I binge-read the entire piece in a weekend! (Who says binging is only for TV content?!) Net net: If you want a book that covers every angle—and every argument—from every side of today’s most important technologies… this is surely the one.

    The Fourth Age is a must-read for anyone who’s interested in the future of AI or of society as a whole because, as Reese explains, we’re at the dawn of a new age of technological advancement. Reese strikes the perfect balance between easy to understand and thorough. It wasn’t preachy or bogged down with technical facts, like a lot of nonfiction books on AI are. Instead, his book kept me hooked and was well-written in layman terms. Even though I have no background in AI or in computers, I was able to follow and understand Reese’s carefully laid-out arguments and thought process. In media, we often only see polarized views with outlandish claims on the future of AI. Thus, The Fourth Age is especially eye-opening because Reese maintains a neutral point of view and provides the reader ample evidence to support his ultimate conclusions. He entertains all possible scenarios/theories regarding unemployment, affluence, quality of life, and conscious AI. Then he gives the reader the comprehensive rundown on how likely they are to happen. But what fascinated me the most was Reese’s exploration of the big philosophical questions that the future of AI raises. He challenges us to reconsider what it means to be conscious and what it means to be a human. We often think of computers as cold and mechanistic, embedded in the STEM field, but Reese shatters that notion by showing how fundamentally connected philosophy and AI are in an incredibly provocative way. Overall, The Fourth Age is an informative, gripping read that sheds light on the murky world of AI.
