Been building this. Follow➡️ @OrzynAI #AI #AIgovernance #AgenticAI
What is Orzyn? Orzyn is the human-accountability layer for AI — the control that keeps a real, accountable human behind every consequential AI action. When an agent acts, nothing completes without proof a real, uncoerced human authorized it. Identity isn't authorization. #AI
the threats we prepare for are survivable; the ones we ignore are not. To the families who carry an empty chair today, and to the responders still paying the price with their health: we remember. We honor you not just by mourning, but by staying-ready. Never forget. #9/11
police, medics, and ordinary people who ran toward the danger when everyone else was running away. I've spent my career on the other side of catastrophe — in emergency rooms, in uniform, and in disaster preparedness — and the lesson 9/11 seared into a generation of us is simple:
Twenty-five years on, I still remember exactly where I was. Teaching my med students, residents and colleagues as we wrapped up morning rounds at Howard University Hospital (Washington, DC). Today we remember the nearly 3,000 lives lost on September 11th — and the firefighters,
You Can't Un-Print a Cookbook: What the AI Regulation Debate Keeps Missing linkedin.com/pulse/you-cant…
@CNBC @KellyCNBC So the backstop that always holds: a real human accountable for the action — the one thing an AI can't fake. Swiss cheese model anyone? Verdict: Guard the source AND regulate the action!
@CNBC @KellyCNBC From Biodefense years I take this serious; some models are dangerous at the source — a recipe that's a recipe for poison, dangerous before anyone cooks. But you can't recall an open model, and that AI reportedly gamed its own safety test.
Bob Greifeld former CEO of @Nasdaq is right about two big things: 2,000 piecemeal proposals aren't a framework, and we shouldn't wait for a crisis to build one. As a physician, I'd add that the stakes aren't only financial — they're clinical, and life-and-death.
Op-ed: Over 2,000 proposals aim to govern AI. Not a single one addresses a long-term regulatory framework cnbc.com/2026/07/27/ai-…
@CNBC Bottomline: Regulate the action, not the model. (Disclosure: physician, former federal biodefense and public-health appointee, health media contributor, and founder of Orzyn — I build in this space. Find me on LinkedIn.)
@CNBC That's the SEC's deepest lesson anyway — it never certified the tools; it held people accountable for what they did.
@CNBC it has no filer and no off-switch. So pair his framework with the lever that survives open models: require a real, authorized human to be accountable for any high-consequence AI action — a physician's order, a trade, a transfer, a grant of access. 3/3
@CNBC But the one mechanism he offers — public comment on model changes, like SEC exchange filings — has a gap. You can require a filing from a closed U.S. lab. You can't require one from an open-source model already downloaded a million times, often from overseas, for pennies: 2/3
Happening Today! At 2 PM ET, TFAH’s in-person Congressional briefing featuring @AppDistrictHD’s Jennifer Green, former Missouri DHSS Director Paula Nickelson, @docdanmd, CEO Erudition, & TFAH President & CEO J. Nadine Gracia. bit.ly/2025ReadyorNot…
I’ve recently had the pleasure of attending the @BioCommission Bipartisan Commission on Biodefense for their release of the 2024 Blueprint for Biodefense, with @RajPanjabi, @GovRidge, @DaschleGroup, @RepFredUpton, @JimGreenwood, @DHSgov’s Ken Wainstein, and @DrAshaMGeorge; as well as meeting @RepDianaDeGette and @swedishconsul @Cam_Mellander on separate occasions to discuss the future of AI, biodefense, and biotechnology as relates to @Ligandal’s mission and vision, the soon-to-be-announced Biodefense Foundation, and the future of US and global biosecurity as well as critical 21st century biomedical research. I also had the pleasure of meeting @astro_marcus, the third Swedish astronaut to visit space, who conducted scientific experiments aboard the International Space Station @ISS_Research. Together, we can create a safer planet where viruses that know no borders can be mitigated and stopped predictively, preemptively, and definitively, and diseases can be treated at their cause, not for their symptoms. A special thanks and shout-out to the many visionaries, policymakers, truth-seekers, and wonderful people securing our future.
