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.
