Lovable CEO Anton Osika said AI development should slow while safety cannot be guaranteed.

OpenAI and Anthropic's leaders have not publicly addressed Coxon's warning, which sparked a big debate.

Most AI leaders have stayed quiet since Jacob Coxon accused OpenAI and Anthropic of " gambling with our lives " — except for one: Lovable CEO Anton Osika.

The founder of the Swedish vibe-coding startup wrote in a LinkedIn post on Thursday that warnings such as Coxon's "deserve to be taken seriously," and backed slowing AI development.

Coxon, a 27-year-old who spent around three years as a researcher at OpenAI and Anthropic, quit the latter this week.

He warned the two labs were racing toward self-improving superintelligence without acting responsibly.

"The people building AI earnestly believe that it could kill us all by the end of the decade," he wrote on X on Wednesday.

"This is not a marketing stunt." It set off a fierce debate among AI researchers , policymakers, and tech observers.

Several current and former Anthropic employees publicly endorsed parts of Coxon's warning.

Others like Gary Marcus, an AI researcher and author, said there was "no realistic scenario" for near-term human extinction, and Melanie Mitchell, a professor at the Santa Fe Institute, similarly called extinction fears "far-fetched." On Thursday, Osika wrote in the post, which featured screenshots of Coxon's X thread: "Decisions that could affect everyone deserve public accountability.

The people building the most powerful systems should have to demonstrate that they can keep them under control." Osika added: "As a European founder, I want our leaders to hear this: you have my support in pushing for international coordination, including slowing dangerous development when safety cannot be demonstrated." Evan Hubinger, who leads Anthropic's alignment team, which tests if superintelligent AI follows human values, said he personally believed there was a greater-than-10% chance that AI could kill all humans within the next decade.

He added that Anthropic did not yet have a plan to solve alignment for superintelligence, although it was trying its best.
