After AI

The technology that comes after artificial intelligence is already here. Almost no one understands what it will do.

Everyone is talking about AI. Almost no one is talking about what comes next, and what comes next will matter more.

In After AI, Sui Ruizhé makes a bold and rigorously argued case: artificial intelligence was the final achievement of the classical computing age, not the beginning of the future. The real frontier is quantum computing, the technology that, fused with AI, is moving humanity from discovering reality to engineering it.

This is not science fiction, and it is not hype. Written for the intelligent general reader with no physics required, this book explains in plain language one of the most important and least understood shifts of our time:

• Why the encryption protecting every bank, government, and private message in the world is already living on borrowed time, and why hostile states are harvesting your data today to read it later.
• How quantum computing will transform medicine, materials, and energy, compressing decades of discovery into years.
• The new geopolitics of computation: the quantum arms race, the rise of the first "quantum empires," and why a handful of nations and companies are positioned to dominate the century.
• What "designing reality" actually means for science, for power, for work, and for what it means to be human.

What sets this book apart is its discipline. It refuses both the breathless optimism of the technology industry and the reflexive doom of its critics. It tells you, again and again, what is genuinely real, what is merely marketed, what is near, and what is distant. And it ends with the one question that matters: not whether this future arrives, but who is building it, who it serves, and whether we can become wise enough to deserve it.

If you read one book to understand the next thirty years, read this one.
