Tools for Humanity, a startup co-founded by Sam Altman, has launched its its World eyeball-scanning identity verification system in the US. During an event in San Francisco, Altman reportedly said that World's technology provides "a way to make sure humans remained central and special in a world where the internet had a lot of AI-driven content.

Sam Altman’s project that aims to scan the irises of every single person on Earth in exchange for cryptocurrency has made its debut in the U.S., even as concerns around biometric data collection and processing remain.

The eyeball-scanning crypto play had originally stayed out of the U.S. market amid a more uncertain regulatory regime.
