Twenty-year-old Daniel Moreno-Gama was charged with attempted arson and attempted murder after hurling a Molotov cocktail at OpenAI CEO Sam Altman’s San Francisco home on April 10 and trying to break into the company’s headquarters with a chair.
The attack, which caused no injuries, unfolded amid a broader surge in public hostility toward artificial intelligence, with Moreno-Gama carrying an anti-AI manifesto referencing Luigi Mangione, the man charged with killing UnitedHealthcare’s CEO.
San Francisco police arrested two additional individuals two days later after shots were fired near Altman’s property; they were released without charges as investigations continue.
OpenAI’s global policy chief Chris Lehane said in a recent interview that irresponsible discourse about AI risks has real-world consequences, pointing to the attack as evidence that inflammatory rhetoric can inspire violence.
Lehane framed the public debate as split between AI optimists who envision abundance and “doomers” who hold a “very, very negative and dark view of humanity,” arguing OpenAI must better communicate the technology’s benefits to families and society.
But critics note the irony in Lehane’s call for calm, given that Altman himself warned in 2015 that AI would “most likely… lead to the end of the world,” while acknowledging it would create great companies in the interim.
Fortune reports that anti-AI sentiment has been growing for years, driven by concerns over job automation, environmental impacts, warfare applications, and psychological harm, including lawsuits linking AI to teen deaths.
A March NBC News poll found only 26% of voters view AI positively, compared to 46% who hold negative views — a disparity most pronounced among younger Americans facing a difficult job market.
The backlash reflects a broader public unease fueled by AI companies’ own messaging, which for years has emphasized existential risks like bioweapons, cyberattacks, and human extinction — rhetoric some argue functions as effective marketing despite its alarming tone.
Anthropic’s recent launch of its “Mythos” model, described as too dangerous for public release, exemplifies this trend, even as critics question whether such warnings amplify fear more than they inform.
Altman responded to the attack by sharing a photo of his family, including his infant daughter, in a blog post hoping the image might deter future violence, regardless of opinions about him or AI.
How the attack unfolded according to official reports
Moreno-Gama traveled from a Houston suburb to San Francisco, arriving at Altman’s home around 3:45 a.m. On April 10, where surveillance footage shows him throwing a lit Molotov cocktail that bounced off the building.
He then proceeded to OpenAI’s headquarters about three miles away, arriving near 5 a.m., where he attempted to smash glass doors with a chair before security intervened.
According to the federal complaint, Moreno-Gama told guards he intended to burn the building down and kill anyone inside.
His parents stated he had recently experienced a mental health crisis, a factor cited in his defense as the case proceeds.
Moreno-Gama has not entered a plea and faces a potential life sentence if convicted on the charges of attempted arson and attempted murder.
What polling data reveals about public trust in AI
The March NBC News survey showed a 20-point gap between negative and positive views of AI, with 46% of voters expressing unfavorable opinions versus 26% favorable.
Only the Democratic Party and Iran received lower favorability ratings in the same poll, underscoring the depth of public skepticism.
Anti-AI sentiment is especially strong among younger voters, many of whom are navigating a labor market reshaped by automation and gig economy pressures.
Fortune notes this distrust has been building for years, rooted in tangible anxieties about job displacement, AI’s role in surveillance and warfare, and growing evidence of psychological harm from prolonged AI interaction.
Why AI executives face criticism for their risk messaging
Lehane’s appeal for calmer discourse comes after years of AI leaders highlighting catastrophic risks in congressional testimony and public forums, often while seeking regulatory frameworks and government contracts.
Fortune observes that warning the public AI could cause mass unemployment, enable bioweapons, or end civilization has paradoxically made the technology more appealing to certain investors and consumers drawn to its perceived power.
This dynamic creates a contradiction: companies profit from framing AI as both immensely valuable and existentially dangerous, then express alarm when some members of the public act on the latter narrative.
The Guardian reported Altman’s blog post sharing his family photo as a direct appeal for empathy, attempting to humanize himself amid threats tied to his role as AI’s most visible CEO.
Was anyone injured in the attack on Sam Altman’s home?
No, Altman confirmed in his blog post that the Molotov cocktail bounced off the building and no one was harmed.
What charges does Daniel Moreno-Gama face?
He has been charged with attempted arson and attempted murder under federal and California state law, with a potential life sentence if convicted.
How have AI companies contributed to public fears about the technology?
For years, executives have warned AI could enable cyberattacks, build bioweapons, cause mass unemployment, and lead to human extinction — rhetoric that critics argue functions as both risk disclosure and marketing.
Is the broader anti-AI sentiment limited to extremist acts like the Molotov cocktail attack?
No, Fortune and The Guardian describe a widespread, non-violent backlash rooted in job losses, environmental concerns, psychological harm, and distrust of AI’s societal impacts, particularly among younger generations.
