Picture New York City in the 1880s. You probably imagine cobblestone streets, gas lamps, and the romantic clip-clop of horse-drawn carriages. The reality was a nightmare. The streets weren’t paved with gold; they were blanketed in a ‘warm brown carpet’ of thousands of pounds of horse manure and urine. And if you looked closely, you’d see the rotting corpses of 15,000 dead horses a year—abandoned in the streets until they decayed enough to be cut apart and hauled away.
This wasn’t a dystopian novel. This was the peak of human industrial progress.
The Industrial Revolution promised modernity, but it plunged cities into a primitive, unhygienic hell. By 1894, London had 300,000 horses. New York had 100,000. A single horse produces up to 16 kilos of feces a day. The math was catastrophic. The Times of London predicted that in 50 years, every street in the city would be buried under nine feet of manure.
In 1898, the world’s brightest minds gathered in New York for the first International Urban Planning Conference. Their mission? Figure out how to save the modern city from drowning in horse shit. They proposed limiting horse numbers, hiring more street sweepers, and designing better carts. They debated for ten days. And then they gave up. The consensus was bleak: the modern city had reached its ‘physical limit’ and civilization was doomed to collapse under the weight of its own excrement.
When you are trapped inside a paradigm, you don’t invent the future. You just design a better shovel.
The experts couldn’t solve the crisis because they were trying to optimize the existing system. They were trying to make the horse more efficient. They couldn’t fathom that the solution wasn’t a better horse, a better cart, or a better shovel. The solution was to eliminate the horse entirely.
Within a decade, the internal combustion engine did exactly that. The automobile didn’t solve the horse manure crisis; it made the crisis entirely obsolete.
The apocalypse wasn’t canceled by a treaty. It was canceled by a technology nobody in the room saw coming.
We look back at those 1898 experts and laugh. How could they be so blind? But look at us today. Faced with climate change, urban gridlock, and energy crises, our brightest minds are doing the exact same thing. We’re building carbon-capture vacuums, optimizing traffic lights, and making slightly less polluting versions of the exact same systems that are killing us. We are still designing better shovels.
We are still trying to clean up the streets instead of questioning why the horses are there in the first place. When you are stuck in a systemic crisis, incremental optimization is a death sentence. The real solutions—the ones that actually save civilizations—don’t come from better rules. They come from paradigm shifts that make the problem irrelevant.
True progress doesn’t clean up the mess of the old paradigm. It burns the old paradigm to the ground.
FAQ
Q: Isn't it unfair to compare 19th-century horse manure to something as complex as climate change?
A: It's actually a perfectly scaled analogy. The 1898 urban planning conference was dealing with a life-threatening, system-wide crisis that experts believed was unsolvable. They were right—within their paradigm. Climate change feels insurmountable today because we are trying to tweak the combustion engine rather than waiting for (or aggressively funding) the technological leap that renders it obsolete.
Q: What's the practical implication of this mental model for today's businesses?
A: Stop pouring R&D into making your current broken product 10% more efficient. If your industry is facing a systemic crisis, the winning move isn't a better shovel—it's inventing the technology that makes the shovel unnecessary. Spend your resources on the paradigm shift, not the optimization.
Q: Are you saying we shouldn't try to fix immediate problems and just wait for tech to save us?
A: No, I'm saying stop pretending incremental optimizations are the cure. The 1898 experts wasted ten days designing better street-sweeping rules while the internal combustion engine was already being developed. If you want to solve a crisis, put your weight behind the disruptive tech that makes the current crisis irrelevant, rather than trying to regulate the current system out of its own nature.
