Facebook co-founder Dustin Moskovitz and his wife, Cari Tuna, are central figures in a debate over the influence of the "effective altruism" movement on artificial intelligence policy. This scrutiny follows the resignation of former Anthropic researcher Jacob Coxon, whose departure and subsequent media prominence have raised questions about coordinated efforts to shape legislative outcomes regarding AI regulation.
Parker Thayer, an investigative researcher at the Capital Research Center, characterized the sequence of events surrounding Coxon's resignation as a "very sophisticated and well-funded PR operation." Thayer pointed to the rapid amplification of Coxon's social media post by influential accounts and top lawmakers as evidence of organized messaging rather than organic public concern.
What the Right Is Saying
Conservative critics and free-market advocates view the push for AI regulation as potentially driven by political motives rather than purely scientific consensus. White House AI advisor David Sacks described the current climate as a "panic," noting, "We're in an election season, and there is an incentive for political actors to try and amplify the fear."
Sacks advised a rational approach to the issue, suggesting that fears of AI doom are "overblown." Parker Thayer echoed these sentiments, describing the "effective altruism" philosophy as "cult-like" and suggesting that Silicon Valley elites use the movement to advance specific political goals. Thayer noted that while he did not offer a specific theory for who coordinated with Coxon, the timing and amplification of the resignation message warranted scrutiny.
What the Left Is Saying
Progressive voices and Democratic lawmakers have emphasized the urgency of regulating artificial intelligence to mitigate existential risks. Sen. Bernie Sanders, I-Vt., has publicly supported pausing certain AI developments, stating, "Yes, we must hit the pause button on AI before it is too late."
Jacob Coxon, who spent three years in pretraining research at OpenAI and Anthropic, argued that major AI companies are "racing straight to self-improving superintelligence and gambling with our lives." Coxon stated that the problem of AI safety is "not unsolvable" but requires moderation and deliberate action rather than submitting to the "inevitability of a doomed race."
Rep. Ted Lieu, D-Calif., has advocated for strict oversight, arguing in an opinion piece that AI is "already too powerful" and requires a "kill switch" to prevent disaster. These voices frame the push for regulation as a necessary response to the potential for catastrophic outcomes identified by researchers within the field.
What the Numbers Show
Coefficient Giving, formerly known as Open Philanthropy, serves as the primary funding vehicle for Moskovitz and Tuna, who remain its main funders. According to the organization, its commitment to AI safety, security, and field-building has grown significantly in recent years.
In 2024, Coefficient Giving committed $168 million to these AI-related causes. For 2025, the organization reported committing $351 million, bringing the combined two-year total to $519 million. The organization states it is on track to commit more than $1 billion to AI policy advocacy in 2026.
A 2021 grant application description from Coefficient Giving outlined its interest in funding programs related to "effective altruism, global catastrophic risks, biosecurity, AI for epistemics, forecasting, and other areas." Forbes estimates Moskovitz's net worth at approximately $10 billion.
The Bottom Line
The debate highlights a growing divide over how to manage the rapid advancement of artificial intelligence. On one side, proponents of regulation cite warnings from researchers and significant financial backing from influential philanthropists to argue for immediate legislative safeguards. On the other side, critics argue that the narrative of existential AI risk is being strategically amplified to justify regulatory burdens on the tech industry.
Coxon has denied that his resignation was part of a coordinated PR campaign, stating he acted alone. However, the involvement of figures like Moskovitz and the scale of funding directed toward AI policy through organizations like Coefficient Giving ensure that the question of influence will remain a central issue in upcoming legislative discussions. Lawmakers from both parties, including President Donald Trump and New York City Mayor Zohran Mamdani, have weighed in on the controversy, indicating its broad political reach.
