Worldcoin’s plan to collect biometric data from poor people to bootstrap their system is unethical and raises serious privacy concerns. Their promises to protect users’ data are not enough to ensure privacy and security, and linking immutable biometric traits to financial identities could enable total identity lockout with dystopian consequences. In addition, Worldcoin’s token allocation favors insiders and market makers, indicating that equal distribution among all people is not a genuine goal. Overall, Worldcoin appears to be just another speculative crypto project masquerading as a radical new financial system.
