Even if you assume good-intent from Sam Altman’s WorldCoin (I don’t, but let’s play dystopian’s advocate here), the problem they claim they are trying to solve is ultimately a category error:

The only UBI you need in a physical-resources constrained reality is deflation.

The only credit score system you need in an AI- is organic web-of-trust like emergent systems.

The solutions the WorldCoin team claims to be solving are only problems that exist in the delusional, paternalistic worldview of a technocrat.
