A letter signed by 1,367 researchers and engineers at frontier AI labs, including OpenAI, Anthropic, and Google DeepMind, warned that capability development could rapidly accelerate beyond human ability to understand or control the resulting systems. [^1]

The letter was released last month and highlights the concerns of engineers regarding the pace of technology development. [^2]

On the available record, the signatories appear to view the speed of capability growth as the primary variable threatening human oversight, though the letter does not specify a timeline for when such a divergence might occur.
