Surveillance footage reportedly shows Moreno-Gama near Altman's home before the incident, although the images were initially obscured for identification purposes.


Details of the Attack How the Attack Unfolded

According to Altman's blog post, the attack occurred around 3:45 a.m. on Friday. A police report confirmed that the suspect threw a bottle with a lit rag at the metal gate of Altman's residence located at 855 Chestnut St. in the Russian Hill area. By the time emergency services arrived shortly before 4 a.m., the fire had extinguished itself, but officers found an incendiary device at the scene.


Threats Extended The Threat Did Not Stop There

After the incident, Moreno-Gama reportedly headed towards OpenAI's headquarters in Mission Bay, where he threatened to ignite the building. The San Francisco Police Department confirmed that he made threats to cause significant damage at the company's offices on Third Street, leading to his arrest while he was still making threats.


Investigative Insights What Was the Motive?

As of now, authorities have not disclosed a clear motive for the attack. The investigation is ongoing, and many aspects remain undisclosed. In his blog post, Altman reflected on an "incendiary article" about him that had circulated days before the attack, believed to be a piece from the New Yorker that raised questions about his trustworthiness. He suggested that the rising public anxiety surrounding artificial intelligence might have contributed to the incident, stating, "Someone mentioned that this is a time of great anxiety about AI, making things more dangerous for me. I initially dismissed it, but now I find myself awake at night, realizing I may have underestimated the impact of narratives."


Next Steps What Comes Next

Moreno-Gama is currently in custody as the investigation continues. Authorities have yet to provide additional information regarding his background or the specific reasons behind his targeting of Altman and OpenAI's offices on that fateful morning.
