A clip is going round again describing a 20-year-old who flew from Texas to San Francisco with a manifesto and a list of AI chief executives.

The underlying case is real. It is also from April, the defendant has pleaded not guilty, and no court has found any of it proven. None of that survives the trip to a fifteen-second video, so here is the whole thing.

What prosecutors allege

At roughly 4am on 10 April 2026, prosecutors say, Daniel Moreno-Gama, 20, of Spring, Texas, threw a Molotov cocktail at the San Francisco home of OpenAI chief executive Sam Altman.

Police say they found him with further incendiary devices, a jug of kerosene, a lighter, and a written document titled "Your Last Warning" which advocated killing executives and investors in the AI industry and listed names and addresses said to belong to several of them.

We are not reproducing any part of that list, or the document's contents beyond what the charges rest on.

Where the case stands

He faces two counts of attempted murder and nine further state charges, carrying between 19 years and life. Federally he is charged with possession of an unregistered firearm and attempted destruction of property by means of explosives, together carrying up to 30 additional years.

He has pleaded not guilty.

His attorney has called the incident a property crime at best, argued the charges are disproportionate, and cited a mental health crisis.

That is the entire status: allegations, a plea, and a defence position. Nothing has been decided.

The framing that travels with the clip

The captions carrying this story generally supply a cause: that the AI industry marketed itself through fear for years and this is the result.

It is worth separating that into two claims, because they are not the same.

That there is a backlash is documented. Between April and June 2025, 20 proposed data centre projects worth a combined $98 billion were blocked or delayed by local resistance. That is a measurable phenomenon with planning records behind it.

That the industry's rhetoric produced this specific attack is a causal claim about one person's motivation, made by people with no access to him, against a defence that has raised his mental health. It may be right. Nothing published establishes it, and a social media caption is not where that gets settled.

Why the date matters

The attack was in April. The arraignment was in May. It is late August.

A clip that carries no date reads as news. Someone who sees it today reasonably believes an attack just happened, that the AI backlash has escalated this week, and that the situation is more volatile than it is. That is a real distortion produced by nothing more than an omission.

It is the same mechanism we wrote about in the reels claiming a company had built something too dangerous to release: a true-ish core, stripped of the qualifiers that make it accurate, travelling faster than the original.

The part worth taking seriously

Underneath the recirculation, the substance is not trivial.

Somebody wrote down the names and addresses of technology executives and, on the prosecution's account, acted on it. Whatever a court decides about this defendant, executives in the sector have had to think about physical security in a way they did not two years ago, and that shift is real regardless of how this case resolves.

It sits alongside the planning fights, the regulatory penalties arriving at a new scale, and the general sense that the argument about AI has stopped being conducted only in essays. Most of that argument is lawful and ordinary. This case, if proven, is not part of it — it is the thing that ordinary opposition gets tarred with, which is its own cost.

What is not established

  • Anything alleged. He has pleaded not guilty; there is no verdict.
  • His motive, beyond what the document is said to contain.
  • The document's length. Page counts circulating with the clips are not something we could confirm.
  • Whether domestic terrorism charges will follow. Prosecutors have left the possibility open; nothing has been filed.
  • Any connection to a group or movement. None reported.
