In The God Test, Robert Wright argues that artificial intelligence is best understood not merely as a powerful new tool with good and bad applications but as an evolutionary event, possibly the most important inflection point in the history of life on Earth. Building on the thesis of his earlier book Nonzero, that biological and cultural evolution have a direction, pushing toward greater complexity and wider webs of cooperation, Wright asks what it means that this process may now be producing a vast, alien, and potentially godlike intelligence. The test of the title is whether humanity can rise to the occasion: whether nations and their leaders can overcome rivalry and build a sufficiently global and cooperative approach to shepherd into existence something benevolent rather than catastrophic. Wright weighs the arguments for and against racing ahead with AI development, drawing on figures ranging from the Jesuit paleontologist and mystic Pierre Teilhard de Chardin, who imagined humanity converging toward a planetary mind, to contemporary AI leaders such as Anthropic's Dario Amodei. He also makes a spiritual case, suggesting that confronting this challenge could restore something missing from modern life, a sense of shared purpose and moral seriousness. Wright, a journalist and author whose earlier books include The Moral Animal, The Evolution of God, and Why Buddhism Is True, has long worked at the intersection of evolutionary psychology, religion, and geopolitics, and this book brings those interests together. Readers may dispute its grand claims about evolution's direction, but it offers a distinctive, big-picture framework for thinking about AI, international cooperation, and meaning.
