Prosecutors cite a violent anti‑AI manifesto as evidence of intent.

Sam Altman, patron du géant de l'intelligence artificielle OpenAI, à Washington, le 11 mars 2026

Overview

  • Sam Altman’s San Francisco home was hit by a Molotov cocktail on Friday in an attack that caused no injuries, and the suspect then walked to OpenAI’s headquarters and tried to smash the glass doors with a chair.
  • Police arrested 20-year-old Texan Daniel Moreno-Gama with a can of kerosene, a lighter, and a document titled “Ton dernier avertissement.”
  • Federal prosecutors charged him with attempted destruction of property using explosives and possession of an unregistered weapon, and they say he came to burn the site and kill people inside.
  • The Justice Department says the document promoted violent opposition to AI and urged murders and other crimes against executives and investors, and it included a list of names and addresses.
  • After the attack, Altman called on critics to lower the temperature and asked for a de‑escalation of rhetoric toward the AI industry.
