News Summary

• Geoffrey Hinton gave the United States Senate a deadline on Wednesday, and it was shorter than the legislative calendar.
• He was speaking at a closed, hour-long briefing at the Capitol convened by Senator Bernie Sanders.
• Because it was a briefing rather than a hearing, there is no transcript, no sworn testimony, and no written submission; the account rests on what attendees described afterward.
• Hinton presented alongside Max Tegmark, the MIT physicist who co-founded the Future of Life Institute, and the independent risk researcher Ajeya Cotra.
