How did we exchange information before photography,
before print,
even before writing?
How was truth represented in a world of stories, myths and oral traditions?
For most of human history,
truth wasn’t a fixed point;
it was negotiated within a tribe,
verified by proximity,
and sustained by trust.
In that sense,
we may be returning to an ancient condition:
truth as local, not universal.
This isn’t necessarily the apoc…

Abstract: The Price of Anarchy (PoA) is a standard metric for quantifying inefficiency in socio-technical systems, widely used to guide policies like traffic tolling. Conventional PoA analysis relies on exact numerical costs. However, in many settings, costs represent agents' preferences and may be defined only up to possibly arbitrary scaling and shifting, representing informational and modeling ambiguities. We observe that while such transformations preserve equilibrium and optimal outcomes, they change the PoA value. To resolve this issue, we rely on results from Social Choice Theory and define the Invariant PoA. By connecting admissible transformations to degrees of comparability of agents' costs, we derive the specific social welfare functions which ensure that efficiency evaluations do not depend on arbitrary rescalings or translations of individual costs. Case studies on a toy example and the Zurich network demonstrate that identical tolling strategies can lead to substantially different efficiency estimates depending on the assumed comparability. Our framework thus demonstrates that explicit axiomatic foundations are necessary in order to define efficiency metrics and to appropriately guide policy in large-scale infrastructure design robustly and effectively.

Tech journalist Gil Duran outlines a disturbing theory
that a growing number of Silicon Valley elites are pursuing a vision of power
not rooted in the common good,
but in profit, feudal hierarchy, and total control of the platforms that define daily life for hundreds of millions of people.
Duran dubs this emerging ideology the “Nerd Reich”
— a slurry of right-wing ideas championed by ruthless tech overlords like
Palantir founder Peter Thiel,
Tesla an…
