A meditation on fear, physicality, and the value that cannot be digitised.
There is a fear I recognise immediately when I see it in people's eyes. It is not the fear of failure, nor of poverty in any classical sense. It is something subtler, more modern: the fear of becoming irrelevant. Of being overtaken by a machine that never tires, never asks for a pay rise, and has no need of weekends.
I understand where it comes from. News headlines are engineered to amplify it. Algorithms have learned that anxiety sells better than calm.
But there is a deeper logic at work — one you discover not in the news feed, but in physics and in the real economy. A logic that Travis Kalanick, the founder of Uber, once captured in a sentence I turned over in my mind for a long time after I first read it: the more we automate, the more valuable the people who cannot be automated become.
Not less valuable. More valuable.
That changes everything — if you are willing to sit with the idea long enough to let it settle.
The thought experiment that reset my frame
Imagine an extreme scenario. Tomorrow morning, every profession is automated. AI architects, AI engineers, AI accountants, AI project managers. All of them — except one: plumbers.
What happens?
Algorithms design a thousand buildings a day. Structural calculations are run in milliseconds. Materials are ordered automatically, delivered by drones, stacked by robots.
And everything grinds to a halt at the pipe.
The actual joining of conduits, the soldering in cramped spaces, the adaptation to an old building full of surprises inside its walls — all of this remains impossible to automate within any visible horizon. Not for want of engineering ambition, but because of real physical constraints: infinite variability, unstructured environments, tactile decisions made in real time.
The result? Not that plumbers become useless. The result is that they become the bottleneck of the entire built economy. Thousands of projects stalled. Billions waiting. And a handful of people with a wrench who can unblock everything.
