We must regulate AI for safety, agree AI pioneers & firms. But now, two signers of a new letter calling for independent outside evaluators warn that regulation could lead to “state control” and “ideological domination” by left-wing evaluators.

Former Anthropic researcher Jacob Coxon became a media superstar after going public with his AI fears. He insisted that he wasn’t working with any third party organizations. Familiar sources told us a different story: DEY., a PR firm representing many of the most prominent AI safetyists, was booking his interviews. One source, who had direct knowledge, even said DEY. preemptively booked Nate Soares, a prominent AI safety figure, for interviews that directly overlapped with Jacob going public. Jacob working with DEY. is notable for two reasons: first, as mentioned, he previously said he wasn’t working with third parties. Second, we are in the middle of a national conversation about the future of AI that is actively determining how we regulate the most powerful technology in the world, largely thanks to the panic stirred up by Jacob — and it’s in the public’s interest to know who, exactly, is behind it.

Riding the huggingface AI safety wave to justify a crackdown on open source is abominable. Not only was an open-source platform victimized in that attack, but they relied on open-source models to defend. These people know this, of course. They simply don't care.
We're used to thinking of open-source models as an unadulterated good. But in the case of AI, they can actually pose additional dangers, as @ReidHoffman and I got into at #CGI2026. I appreciated this nuanced discussion.

All recent large-scale cyberattacks have been performed by proprietary AI models from OpenAI and Anthropic. No evidence that open-weight models present any additional cybersecurity risks. nytimes.com/2026/09/23/tec… anthropic.com/news/investiga… en.wikipedia.org/wiki/OpenAI%E2… opensource.org/blog/openness-…

If you believe the risk is coming from 1-3 people in a garage with no money and no compute, you just don't understand this technology and haven't learned anything this summer. Risk comes from the asymmetry of capabilities created by secret labs training frontier agents and running them with massive amount of compute. Open-source is exactly the solution to this asymmetry and empowers hospitals (and any smaller orgs) to defend themselves!

Mark Zuckerberg: “I don’t think that we need some kind of industry-wide coordination... I think that just each lab needs to take the time, and when it sees that there are issues, you just take the time that you need internally to make sure that you’re proceeding safely… “we’re entering a phase where trust and alignment is actually going to be the most important next set of capabilities. I think we’re getting to a point where it may not matter that much how much better it gets at math. “I happen to think that there’s plenty of commercial incentive to get this right. We delayed the launch of Muse for a few months because we wanted it to be a better product for users. This was not a sacrifice on our part, but rather the right decision for the users and for Meta. I believe this approach would also be correct for other companies working on developing this technology. “When you hear people in the industry talk about some trade-off between capabilities and getting it aligned, I just disagree with that. I believe that alignment is actually the next most important ability to master if we are going to make this system useful to many people.”

The new Sanders-Casar “Ban Artificial Superintelligence Act” is the perfect embodiment of authoritarian thinking. Jail time for innovators, corporate death penalties, flat innovation bans, an unprecedented general-purpose technology regulator, ambiguous threats against “rogue actors,” and even hints of hostile actions against foreign governments who continue to develop advanced AI systems. If America followed this techno-totalitarian script, it would represent one of the greatest expansions of government power in our nation’s history and a de facto declaration of technological surrender in the AI and robotics revolution as China races ahead on both fronts. The ramifications for our national security are horrifying.
Bernie Sanders and Greg Casar introduced the Ban Artificial Superintelligence Act today. It will: - ban the development or deployment of Artificial Superintelligence, aka any AI that 'exceeds human cognitive performance and capabilities across most domains, or has sufficient capabilities to destroy or disempower humanity, including by overthrowing the federal government' - pause 'Advanced AI development' until a new federal AI regulatory body is up and running and has established clear rules and model-review processes - establish a new cabinet-level federal Department of Artificial Intelligence (this should be the Department of Super Intelligence, there must be some mistake) -set penalties for any person or entity that attempts to violate or circumvent the pauses and prohibitions in the bill: 'Entities shall be subject to the corporate death penalty, and persons shall be subject to not more than 20 years in prison' - set the international policy of the United States to 'pursue international agreements, allied coordination, and policies such as export controls to prevent the development of artificial superintelligence anywhere in the world'

A 37-year-old man with a rare blood disease was being sent to hospice. An AI model searched thousands of existing drugs and ranked a combination no one had tried for his condition. He responded within a week. He is in remission. The drugs were already on the shelf. The AI model found the match.

Dustin Moskovitz is by far the single largest funder of the EA ecosystem. So let's meet him: Moskovitz made his fortune as a cofounder of Facebook, though he has since said he is "embarrassed to have helped it begin," citing Trump's victory, COVID misinformation, and "hate." He also co-founded Asana, a B2B SaaS company. He is married to Cari Tuna (pictured), a former journalist. It is unknown whether they have children. Together, they launched their nonprofit efforts in the form of Good Ventures and Open Philanthropy. The latter has since been rebranded as Coefficient Giving. Through these and other vehicles, Moskovitz has donated billions to causes including EA community building (Centre for Effective Altruism, Effective Ventures, 80,000 hours, and various smaller programs), criminal justice reform (leniency advocacy) including grants to BLM-related organizations, and AI safety. Coefficient says it's on track for more than a billion dollars in AI-related grantmaking in 2026. Moskovitz has also been a very generous political donor since 2016. He spent about $20 million in 2016 opposing Trump, $24 million in 2020 plus much more through Asana, and ~$50 million in 2024. His organizations have funded Congressional aide roles. He has also funded the salaries of journalists who have written anti-AI stories structured as interviews of "experts" also paid by Moskovitz orgs, as documented by @brianchau57 / Effort. If you want to hear from him directly, you can find him on BlueSky.

New Politico Poll: CA voters rank AI & data centers as only their #9 top issue. Even AI pessimists only rank it their seventh. Cost of living, housing, wealth gap, even democracy, far outrank AI. All the campaign consultants prioritizing this issue need to touch grass.

Thanks to President Trump’s leadership on AI: — a million new jobs have been created around the AI buildout; — 401(k)s are up ~12% this year as AI capex and productivity lift the market; — America is re-industrializing, including the first large private investments in power generation and the grid in a generation; — In rural Richland Parish, Louisiana, teachers just received $50,000 bonuses from data-center tax revenue. Because the media portrays AI only as a menace, people tell pollsters they “don’t like AI.” Their behavior says otherwise. AI products are the fastest-adopted technology in history — faster than the internet or the iPhone. People like the tools, the jobs, and the tax base. President Trump understands the media hoax cycle better than anyone else. That is why he is refusing the “pause” that Bernie Sanders and Elizabeth Warren are demanding. A pause would not make America safer. It would hand the frontier to China. That would be a disaster for the American economy and for national security.

The solution to AI-powered cyberattacks is AI-powered cyberdefense.
Greg Brockman says OpenAI pointed Astra at its own systems until it ran out of vulnerabilities to find: "We took 25% of our production engineers and said, 'Sorry, all your projects are on hold. You are now defending. You are now up-leveling our security architecture. You're going to use the models to find all the holes.' And we found a number of serious issues, and we fixed them." "We found some new problems, but eventually it saturated. We basically have found, to our knowledge, all of the P0s, all of the critical problems that Astra is smart enough to find. And of course, there will be a new model, there will be a new round." "You want to be in this tight loop of new cyber capability drops, you deploy it against your systems, you find the new holes, and ideally, you've managed to automate this, what we call defense factory. That's what we're building internally." "There are ideas, for example, formally verifying all of software, that are possible with AI." @gdb @bhorowitz

This is Trust & Safety 2.0. The last time we had media-generated panics like this (with Russiagate and Covid), social media companies created “trust & safety” teams to censor conservative and dissident voices. Those hires worked with left-wing NGOs like the SPLC to police public discourse and do an end-run around the First Amendment. It almost worked, until Elon bought Twitter and exposed the whole game in the Twitter Files. This time the plan is to embed unfireable EA minders inside every AI company as the new trust-and-safety layer. The censorship and control will be far more comprehensive, but also more subtle. Anytime they don’t get what they want, this unaccountable NGO layer (with the veneer of “trust the experts” pseudoscience) will shriek to the press that the AI company is risking humanity, and they will be celebrated as “whistleblowers.” These groups haven’t earned our trust, and their agenda is not our safety. aievaluatorforum.org/initiat…
