Modern cities are the most complex and fragile structures ever built. A single power failure can cascade into chaos. A single pandemic can turn density into a death sentence. A single metre of sea-level rise can displace hundreds of millions.

But for the first time in ten thousand years, there is an alternative.

THE LAST CITY describes a civilisation in which every home generates its own energy, harvests its own water, grows a portion of its own food, recycles its own waste, monitors its own health, and connects to the world by satellite. These autonomous homes, grouped in small clusters of chosen neighbours and scattered across the landscape, replace the fragile concentration of urban life with the distributed resilience of a network that has no critical node.

Drawing on a companion academic paper that provides the formal mathematics, systems theory, and legal framework, Boris Kriger builds the case in plain language: why cities are failing, what the autonomous home looks like, how it is funded (through a single, invisible transaction tax that replaces the entire existing tax system), how universal basic income becomes fiscally possible, where millions of homes can be sited, how drone logistics and electric air taxis liberate settlement from roads, and why the rising sea — far from being merely a catastrophe — is the catalyst that can drive humanity toward a fundamentally better way of living.

This is not utopia. Utopia is static. This is adaptive — a civilisation that evolves, experiments, and improves. It is grounded in engineering, economics, evolutionary psychology, and international law. It is supported by a complete model law ready for legislative adoption and a set of patent targets that map the inventions still needed.

The question is not whether this is possible. It is whether we will choose it.
