Sam Kirshner

Sam Kirshner is an American activist known for his opposition to the development of artificial superintelligence. He co-founded the organization Stop AI in 2024, which advocates for a global moratorium on the advancement of superintelligence technology. Kirshner has been described as a proponent of nonviolent activism, engaging in activities such as distributing leaflets and organizing demonstrations. However, he has faced personal challenges, including a reported crisis of faith in nonviolent methods, leading to his expulsion from Stop AI. His recent disappearance in San Francisco raised concerns among his peers, particularly after he made threats against AI developers and was involved in a violent altercation with the group's new leader.
