Canadian professors Yoshua Bengio, Geoffrey Hinton and Gillian Hadfield signed the statement along with researchers from China, the EU, U.S., and U.K. Their open letter was published Monday, following a meeting of the International Dialogues on AI Safety in Venice earlier this month. (The Logic)

Talking point: Many of the signatories have been the loudest voices raising concerns about AI’s potential to harm humanity; their claims have inspired governments to hold summits and set up institutes focused on the safety of the technology. The researchers say that’s a good start, but more action is needed. They want governments to write international rules to stop the development of AI models that could cause catastrophes, and set up domestic authorities to spot and react to incidents involving the technology. Other researchers argue regulators should focus on the ways AI is already harming people today, rather than science-fiction scenarios.
