Proton CEO Is In ‘Full AI Psychosis’

October 30, 2026

According to 404 Media, Proton CEO Andy Yen is aggressively pushing AI adoption while fostering what workers describe as a culture of fear that discourages raising security concerns or challenging leadership. The investigation is based on interviews with eight current and one former Proton employees, as well as internal Slack chats, meeting recordings, and an AI manifesto written by the company’s CTO. Longtime Slashdot reader devnulljapan summarizes the findings: Engineers at Proton, which makes the encrypted email service Proton Mail and a suite of privacy- and security-focused products, including an encrypted drive service, an authenticator app, and a password manager, are being pushed to “stop lovingly handcrafting all our code and use AI more.” Workers describe an environment where employees have genuine concerns about security or being asked to develop security products with AI but feel unable to voice them, lest Yen berates them in front of everyone or threatens their employment at the company. “The CEO is in full AI psychosis and has been for a while now,” one of the sources told 404 Media. Yen reportedly dismissed an employee’s request for additional security testing before releasing new code, calling it “bullshit and loser thinking” and insisting that “only losers think like that.” In a separate exchange over Proton’s post-quantum encryption rollout, Yen criticized how the company communicated the feature’s limitations and told employees that “perception is more important than truth, the truth doesn’t matter if you don’t win on perception.”

“The train is coming, get onboard or get crushed. Don’t be the professional fax machine operator in the internet age,” Yen wrote to the security Slack channel. “I think by the end of this year most developers stop programming and start writing specs for tests that AI will code and run, to validate AI written code that humans will no longer be able to review. This will be the last year that we hire engineers, and starting next year we hire what we used to call product managers, to build things with AI.”
