Why Machines Will Never Rule the World

Why Machines Will Never Rule the World — Artificial Intelligence without Fear Jobst Landgrebe & Barry Smith · Second Edition · Routledge

We stock the book on building MCP agents. This is the book arguing they will never wake up.

Landgrebe and Smith make a mathematical case rather than a sentimental one: an artificial intelligence that could equal or exceed human intelligence is impossible. Human intelligence is a capability of a complex dynamic system — the brain and central nervous system — and systems of that kind cannot be modelled mathematically in any way that lets them run inside a computer. The argument draws on mathematics, physics, computer science, philosophy, linguistics, biology, and anthropology.

The first edition appeared the same week ChatGPT was released. This second edition applies the argument directly to large language models, making the case that AI systems are best understood as pieces of mathematics — which cannot think, feel, or will.

New in the second edition:

• Extends the original argument to large language models
• Adds a treatment of practical intelligence — knowing how versus knowing that
• Argues that “AI ethics” should be relabelled “ethics of human uses of AI”
• A new chapter on the essential limits of physics, grounding the book’s core claims
• Dismantles the idea that we might already be living in a simulation

The authors are not doomsayers in either direction. Their closing chapter surveys what AI genuinely can achieve for human benefit — all of it without superhuman systems, which they hold to be as impossible as machines that could will a takeover.
