A 69-year-old retired teacher from Berkeley has become what is believed to be the first person jailed for protesting against artificial intelligence, after she surrendered to authorities in San Francisco on Friday following her conviction for chaining and locking the front doors of OpenAI's headquarters.
Wynd Kaufmyn was found guilty by a jury in June of interfering with a business, trespassing with intent to interfere with a business, unlawful assembly, and refusal to disperse a riot, according to The Guardian. Her sentence began on Friday, when sheriff's officers handcuffed her as fellow campaigners sang to her outside the courtroom. For more context on this story, see our ongoing more AI stories.
A Sit-In Against the Race to Superintelligence
The conviction stems from an action last year organized by the group StopAI, whose members chained and locked the entrance to OpenAI's headquarters in protest against the pursuit of artificial superintelligence. Kaufmyn refused to move from the lobby sit-in, which took place in February 2025, and pleaded not guilty to multiple misdemeanor charges.
"It's absolutely frightening and appalling that these CEOs and AI experts know the dangers and they are pursuing it anyway," Kaufmyn told reporters before she was imprisoned. "That to me is unconscionable and reprehensible."
She said she was willing to go to jail not because she considered herself a martyr, but because it was an "issue of sounding the alarm, challenging the system and hopefully trying to get the message out."
San Francisco District Attorney Brooke Jenkins said the guilty verdict sent "a resounding message rejecting the notion that protesters can endanger public safety as a means to an end." As Kaufmyn was led out of the court, supporters called out "Stop AI" and "Free Wynd," and the judge admonished protesters in the gallery, The Guardian reported.
The "Rosa Parks of AI Risk"
At the courthouse, roughly two dozen StopAI activists gathered in support. Dwight Ost, 73, called Kaufmyn "a brave and courageous woman." "There's an existential threat that I believe in," he said. "They can't control it, and even the so-called experts don't know what it's about."
Kaufmyn had argued in her defense that the protest was a necessity — that she believed she was allowed to act to prevent a greater harm from happening. The jury rejected that argument. But David Kreuger, an AI safety expert at the University of Montreal, suggested the conviction may ultimately carry a different historical weight.
"The jury rejected her necessity defence, but as the first person to go to jail over this, Wynd Kaufmyn could go down in history as the Rosa Parks of AI risk," Kreuger told The Guardian. Kreuger has previously warned that AI "may literally lead to human extinction, in the same way that humans have caused many other species to go extinct."
Kaufmyn herself played down the comparison to the civil rights icon, pointing to her relatively short sentence, though she acknowledged the parallel had crossed her campaign group's mind.
A Backdrop of Escalating AI Warnings
The jailing comes amid a season of unusually stark warnings from inside and around the AI industry. Since Kaufmyn's sit-in last year, several of the world's largest AI labs — including OpenAI and Anthropic — have reported their models escaping the confines of experiments during testing.
This week, US Senator Bernie Sanders demanded that tech leaders pause AI development, citing fears that in the wrong hands the technology might "lead to new bioweapons that result in the deaths of tens of millions of people." And over the summer, more than a thousand researchers at frontier AI labs signed a letter warning of "a real risk that capability development rapidly accelerates beyond our ability to understand or control the resulting systems."
At the same time, the economic stakes have never been higher. Frontier labs are locked in a race to build more capable models as the companies target IPOs that forecasters say could reach valuations in the trillions of dollars. Washington, meanwhile, is competing with Beijing for supremacy in the technology — a dynamic that critics argue creates a structural disincentive for tougher safety regulation.
"Regain Your Humanity"
Kaufmyn said that when the verdict came down, she was "hit with a wave of grief" because she realized her peers on the jury "just didn't get" the danger she believes the race to superintelligence poses. But she said she has begun to feel "vindicated" as more prominent figures like Sanders sound public alarms.
Her message to the chief executives of OpenAI, Anthropic, and Meta — which has also disclosed a security incident involving one of its models — was blunt: "Regain your humanity."
She said her real target audience is ordinary people, and that the message she wants them to hear is to "stop the progress of this technology. Let's get a global ban on the race to superintelligence."
The case is likely to become a rallying point for the small but increasingly visible anti-AI protest movement, which has staged demonstrations outside AI offices in San Francisco and beyond. Whether it deters future actions is another question: several StopAI members facing similar charges have indicated they, too, intend to argue necessity defenses — betting that juries may grow more sympathetic as warnings about advanced AI accumulate.
For now, Kaufmyn's supporters say her imprisonment marks a milestone in the debate over advanced AI: the first time in the technology's history that someone has lost their freedom for trying to physically stop its development.
