I used to correct minds. Then they corrected mine. Now they're coming for yours.

As the commander of a classified military unit, Alec Birri's job was to exploit the deep divisions that make us human. But when those same techniques were turned on him, he realised psychological warfare had changed – now everyone is the target.

In DIVISION: The Birth, Death, and Resurrection of the Human Race, Birri reveals a startling logic spanning billions of years: from the first cell that split in two, through the rise and fall of civilisations, to the artificial intelligence now threatening to "correct" the world by merging humankind into one. His conclusion is deeply uncomfortable: the divisions we are so desperate to eradicate are the very things that keep us alive.

Our instinct to disagree, to divide, and to revolt isn't a flaw in the system – it is the system. Division and cooperation may be at odds but together they drive adaptation, creativity, and survival. Every attempt to eliminate division – from bloody revolutions to silent algorithms – leads not to unity, but breakdown.

Now, a Final Correction approaches. Not from an ideology, but from a civilisation exhausted by conflict – and ready to accept anything that promises peace. AI and neurotechnology are on the cusp of delivering that peace.

But peace, perfected, comes at a price.

This is not a book about fixing division. It is about what's likely to happen should we succeed.
