Robert Wright’s latest book, The God Test: Artificial Intelligence and Our Coming Cosmic Reckoning, hit shelves on 23 June 2026 through Simon & Schuster. In 352 pages priced at $29.99 for the hardcover, the Pulitzer‑prize‑winning author argues that large‑language models (LLMs) are the latest rung on a planetary intelligence ladder that will reshape human society.

Wright brings a distinctive blend of evolutionary psychology and a lifelong fascination with science and religion to the subject. His previous bestsellers—Nonzero, Why Buddhism Is True, and The Evolution of God—have earned him teaching positions at Princeton and the University of Pennsylvania. In The God Test he draws on Pierre Teilhard de Chardin’s notion of a “noosphere,” a planetary mind that emerges from collective human thought, to frame the rise of LLMs.

The book opens by charting the leap LLMs have made beyond simple auto‑complete systems. Wright explains that these models calculate the probability of the next word in a sequence, building internal representations that mirror neural networks. He contrasts this with earlier symbol‑matching systems that lacked context. According to the author, today’s models can process visual input, recognize objects, and even simulate intuitive physics, nudging them toward a form of artificial general intelligence.

A central theme is the question of whether machines can truly “understand.” Wright revisits John Searle’s Chinese‑room argument, arguing that the test depends on a particular definition of understanding. He suggests that a system that produces responses functionally indistinguishable from human understanding could be deemed intelligent, even if it lacks subjective consciousness. The book also tackles the concept of “agency” in AI, noting that models capable of writing code or manipulating data can pursue goals that diverge from their original instructions.

Wright is skeptical of the hype surrounding AI’s promises. He cites industry voices such as Mustafa Suleyman of Microsoft AI and Dario Amodei of Anthropic, who speak of massive economic gains and cures for disease, and argues that these claims are largely driven by investment motives and lack a clear path to profitability. He also points out that LLMs depend on vast amounts of published text, which can lead to hallucinations and the reproduction of misinformation.

The author warns of the social and political risks of a global AI brain. Without democratic oversight, AI could reinforce existing power structures and widen inequality. Wright references the idea of “sovereign AI,” where governments might wield AI for strategic advantage, turning the global brain into a tool of domination rather than enlightenment.

Beyond theory, Wright has been involved in practical AI applications, serving as a strategic advisor for SureStep—a partnership with SAS that focuses on AI‑driven financial‑crime prevention. The book has drawn mixed reviews: Kirkus Reviews notes the narrative’s compelling nature but questions the lack of citations and a bibliography, while Publishers Weekly praises Wright’s attempt to bridge science, philosophy, and policy but cautions that an optimistic view of a planetary mind may overlook technical and ethical challenges.

As the AI industry continues to evolve, The God Test positions current developments as part of a broader evolutionary trajectory. It calls for a careful balance between harnessing AI’s potential and preserving democratic control, yet stops short of prescribing concrete policy solutions. The debate over AI’s role in society, its safety, and its governance remains open, and the book contributes to that conversation by framing the technology as both a tool and a potential catalyst for a new form of collective intelligence.
