David Robinson, the OpenAI staffer who led the writing of safety reports for the company's major product launches, has resigned after three and a half years, publishing his reasons as an essay in The Atlantic. In his telling, he is "something of a cliche": the employee who issues a dire warning while walking out the door.

Robinson's argument goes beyond any specific rule or law. He says OpenAI's culture of fast, trial-and-error deployment — what the company calls "iterative deployment" — guarantees periodic failures by design, and the scale of those failures is growing as systems get more capable. He proposes frontier labs should adopt the layered-redundancy discipline of nuclear plants or busy airports, and notes he never worked alongside anyone at OpenAI who had run a power grid, kept aircraft flying, or prevented a financial collapse.

An OpenAI spokesperson said the company keeps improving safety, pausing training or holding back models when it needs to slow down. The resignation lands in the middle of an escalating safety debate: Jacob Coxon's "gambling with our lives" remarks, Dario Amodei's call for labs to slow capability growth, and this week's non-binding AI safety accord signed with President Trump at the White House.
