What is Sam Altman introducing through his new project in OpenAI?

Sam Altman, CEO of OpenAI, has officially launched Worldcoin’s iris-scanning identity system across the United States, following the clearance of legal hurdles.
Worldcoin, Altman’s second major venture, uses a device called the Orb to scan users' retinas and assign them a “proof of humanity”—a unique biometric ID verifying that they are biologically human.
The initiative is a response to growing fears around the “dead internet” theory—a future where most online activity is generated by bots and AIs. By giving each person a verifiable human ID, the project aims to preserve human authenticity in the digital age.
It’s one of the boldest attempts yet to draw a line between humans and machines in the online world.
