DeepMind researcher Robert O'Callahan quits over pace of AI development

Google DeepMind technical expert Robert O'Callahan has resigned in New Zealand, saying AI's rate of change is too high to justify his work on chip design tools that helped make models cheaper and faster. He calls aiming for superintelligent AI in the near future inherently irresponsible, expects harms to outweigh benefits, and says many DeepMind colleagues share his concerns but rarely speak publicly.
