The book begins audaciously by asserting that the world should be divided into political regions of population no greater than 10 million; because "regions will not come to balance until each one is small and autonomous enough to be an independent sphere of culture".

After this anarchist utopia, the patterns proceed to describe the distribution of towns and cities, responses to large geographic features like valleys versus hilltops, the layout of towns, suburbs, streets, sites, buildings, and rooms, all the way down to types of chairs and the half inch of trim that joins walls of different materials.
It features detours into aged care ("old people everywhere"), political economy ("self-governing workshops and offices"), culture ("dancing in the street").
Maybe the closest software work I've seen with this scope is the "blue book" on Domain-Driven Design, but even that doesn't come close to addressing the political economy of software, or the act of writing code.
And that's probably fine, but it really does put A Pattern Language in a class of its own.
