Nick Pickles, the former head of global affairs at Elon Musk’s social media platform X, is joining forces with one of Musk’s rivals, his fellow OpenAI cofounder Sam Altman.

Pickles, who resigned from X in September, told Reuters on Wednesday that he will serve as chief policy officer for Altman’s Tools for Humanity, the company building the technology to support World Network, formerly known as Worldcoin.

Pickles’s old boss, Musk, and his new boss, Altman, founded ChatGPT creator OpenAI together in 2015 but have since fallen out in a messy legal dispute.

World Network, which has faced scrutiny over its data collection, is ramping up efforts to scan people’s irises, using its “orb” devices, to create World ID.

The ID will serve as a digital passport to prove, in the online realm, that its holder is an actual human being as opposed to an AI bot.

Pickles told Reuters that AI is “on the cusp” of overtaking traditional online defenses to determine whether a user is a real person, such as Captcha puzzles. Once AI can blow through those barriers, trust on the web will further disintegrate.

“It’s imminent,” said Pickles. “Throughout my time at X and at Twitter, one of the consistent issues that kept coming up is, ‘Is this a real account or a bot?’” He added: “I saw every day how this issue is going to be central to the future of online interaction.”
