The Crowded Niche: Why Two Lives Cannot Share One Living
Co-founder of Performance
Abstract
Why can no two species occupy exactly the same niche without one of them disappearing? From finches that split a single island into a dozen specialized trades to firms that differentiate or die, this essay examines the iron rule that identical competitors cannot coexist on a finite resource. Drawing connections between ecology, economics, and the theory of competition, the piece argues that scarcity is the great engine of diversity — that it does not merely divide what exists, but forces every contender to become something new in order to survive at all.
The Quiet Revolution
The interesting thing about the present moment is not that machines have begun to read. They have been reading, in various senses, for half a century. The interesting thing is that machines have begun to write, fluently and at scale, in registers that were once the exclusive province of the credentialed expert.
This is not the threat that the popular press describes. The press worries about jobs, and it is right to worry about jobs, but the deeper transformation is epistemological. What we are watching is the codification of vast tracts of tacit knowledge — knowledge that, until recently, could be acquired only through apprenticeship, immersion, and time.
Once a body of tacit knowledge is codified, it ceases to be scarce.
The Polanyi Problem
Michael Polanyi’s 1958 distinction between explicit and tacit knowledge — we know more than we can tell — has spent most of its life as a footnote in management theory. The current moment promotes it to the centre of the discussion.
The reason is simple. A language model can absorb, recombine, and redeploy every published handbook, every memo, every internal wiki, every line of code that has ever been committed to a public repository. The model cannot, however, absorb the look a senior partner gives a junior associate to indicate that the line of questioning should stop. It cannot absorb the way a clinician knows, before the lab work returns, that the patient has something other than what the chart suggests. These are not failures of training data. They are properties of the knowledge itself.
What the next decade will reveal — and what Performance aims, in part, to chronicle — is how organisations restructure themselves around the new line between codifiable and non-codifiable competence.
A Final Note
We are not Luddites at Performance. The codification of explicit knowledge is, on balance, an extraordinary good — it democratises access to material that was previously locked behind credentials, paywalls, or geography. What we are arguing is more modest: that the codifiable and the tacit are not the same thing, that the difference between them is now economically legible, and that organisations and educators who pretend otherwise will pay a price they cannot yet name.
