Background of AI Activism and Previous Incidents

The incident occurs against a backdrop of escalating tensions between AI companies and activist groups concerned about the rapid development of artificial intelligence technologies. Over the past two years, protesters affiliated with organizations such as Stop AI, No AGI, and Pause AI have conducted demonstrations outside the San Francisco offices of major AI companies, including OpenAI and Anthropic

These groups have expressed concerns that unchecked AI development could pose existential risks to humanity. Their protests have occasionally escalated beyond peaceful demonstration, with activists arrested in February for locking the front doors to OpenAI's Mission Bay office. Earlier this month, Stop AI claimed responsibility for an incident where their public defender jumped onstage to serve a subpoena to OpenAI CEO Sam Altman during a public interview in San Francisco.

Interestingly, hours before Friday's incident, the individual who allegedly made the threat posted on social media that he was no longer affiliated with Stop AI

. In previous Stop AI press releases, this individual was described as an organizer who expressed deep concerns about AI replacing human roles in scientific discovery and employment, stating he would find "life not worth living" if such scenarios came to pass.
