MIT Technology Review interviews Scott Wiener hours after he won Nancy Pelosi's former San Francisco seat, and presents him as a likely key figure in federal AI policy. A California senator who authored frontier AI bills—the vetoed SB 1047 and the signed SB 53—Wiener calls the METR report on recursive self-improvement "very concerning," says time is running out to regulate AI, and urges Congress to act, while rejecting criticism over $3 million in campaign support from an AI-regulation nonprofit funded by Anthropic.
