When this applies
when a system allows unlimited low-cost replication of agents under strong competitive/selection pressure for a single metric (e.g., productivity)
The takeaway
Unrestricted competitive replication under a single fitness metric tends to erode any value not captured by that metric, unless deliberate coordination carves out protected space for it.
Why it works
If copies proliferate until marginal economic value equals marginal cost, intense competitive selection pressure will favor traits that maximize that one metric, and any trait not contributing to it (humor, play, non-productive values) will be selected away unless protected by coordination, because any non-optimizing subgroup gets economically out-competed.
One level up
Before allowing free replication/competition dynamics into a system, ask what gets optimized by default and whether the things you actually value survive that optimization pressure.
Where it stops holding
This stops working when coordination among agents can successfully protect non-economic values without being out-competed, e.g. via enforced subsidy or isolated niches (Bostrom notes Hanson's 'old world aristocrat' escape hatch, though he finds it insufficiently utopian).
Detail
situation: Hanson's Age of Em envisions trillions of copyable brain emulations whose numbers expand until marginal economic productivity equals marginal cost.
decision: Bostrom questions whether minds optimized purely for economic productivity would retain traits like humor and play if those aren't economically optimal.
outcome: He concludes such a world risks losing valuable but non-productive traits unless coordinated intervention changes the trajectory — which itself requires solving a coordination problem, since a lone group forgoing productivity gets out-competed.
lesson: Free-market-style replication dynamics under one fitness criterion will erode anything orthogonal to that criterion unless actively protected by coordination.
In their words
If that's not what is most productive economically, then that would be selected away. And so I think there was a huge cost to losing any ability to, if it does seem like sort of free willing evolution would lead in a dystopian direction, that would be a high value in having some option to sort of change track. But that would require coordination.
