#23 - Musk vs. Altman: Vendetta or Principle?

In April 2026, Elon Musk and Sam Altman faced each other in a federal courthouse in Oakland, California — two men who co-founded OpenAI in 2015 on a shared promise to build AI for humanity, now arguing in front of nine jurors about who owns the soul of it. In this episode, Joel and Stephen go deep on the full story. Who are these two men, really? Where did they come from, what drives them, and were they ever actually compatible? Joel breaks down the founding, the power struggle, and the trial itself — including the Greg Brockman diary entry that's now sitting in front of a federal jury, and the Microsoft partnership restructuring that OpenAI announced on the same morning the trial opened. Stephen, drawing on decades of experience inside technology organisations, gives his unfiltered read on whether this is a values clash, a power struggle, or — as he puts it — just petty bullshit at the highest level of the industry. They also get into what the verdict actually means: whether OpenAI is already too big to unwind regardless of the outcome, why Anthropic may be the quiet winner of this whole saga, and what it signals about AI governance when the most important question in the industry is being decided by a judge in Oakland rather than anyone who was elected to decide it. Stephen's prediction: OpenAI wins. Musk walks away looking like an angry, disgruntled founder. The law book will settle it — and it'll come down to what was written, not what was promised over dinner in 2015. ---------------------------------------- Also referenced in this episode: Van Wijk & Ferreira Gomes, "The GOALS of the Techno-Libertarian", Netherlands Institute of International Relations, 2026 · Drexel & Withers, "Terms & Concerns," Catalyzing Crisis, Center for a New American Security, 2024 · Fuchs, "The World in the Age of Trump 2.0", University of Westminster Press, 2025 · Polan, "Growth's Imagination", Bristol University Press, 2025 Signal — listen wherever you get your podcasts.

#22 — Mythos: The AI Model That Spooked the World

Anthropic built an AI model that can find hidden vulnerabilities in the software running the world's banks, power grids, and governments. They called it Mythos. Then they decided who gets access — and every country outside the US and UK found out they weren't on the list. In this episode, Joel and Stephen break down what Mythos actually does, why the geopolitical fallout was immediate and global, and what it means for the rest of us when a private company in San Francisco becomes the most important actor in global cybersecurity — whether anyone elected them to or not.

#21 – The Altman Problem, the Chip War & the Shoe Company That Became an AI Firm

Sam Altman was fired from OpenAI in 2023 for not being "consistently candid." He was back five days later. The question his board raised never went away — and a recent New Yorker investigation digs directly into it. Joel and Stephen unpack what the reporting actually says, and why it matters that the person running the world's most influential AI company has a documented credibility problem. Then: Elon Musk is reportedly trying to build his own chip factory from scratch — bypassing NVIDIA, ASML, and the entire global semiconductor supply chain. Stephen explains what that actually costs, how long it takes, and why vertical integration might be the only real play. Finally: Allbirds, the wool sneaker company that peaked at a $4B valuation and has since lost 95% of its stock value, just rebranded as NewBird AI. Their stock jumped 700% in a single session. No product. No customers. No revenue in the new category. Signal — listen wherever you get your podcasts.

#20 - Dario, Sam & Karp: Who's Actually Walking the Walk?

In February 2026, Dario Amodei, Sam Altman, and Alex Karp all faced the same external pressure — a Pentagon contract, a binary choice — and responded in completely different ways. This episode uses that moment as an entry point into a deeper question: what does a leader's behavior under real-cost, real-consequence pressure reveal that normal operations never can? Joel and Stephen go through each of the three, examining their backgrounds, what shaped them, and what their public actions that week expose about how they actually lead. From Amodei turning a government blacklisting into $5 billion in monthly revenue growth, to Altman's public walkback of a deal he'd called sloppy hours after signing it, to Karp's twenty-year track record of saying exactly what Palantir does and never flinching — the episode draws out a clear through-line: leaders who are unambiguous about what they stand for create more durable organizations than those who try to be everything to everyone.

#19 - How Anthropic Beat the Pentagon, OpenAI Caved & Palantir Took Over the US Military

In the span of a single week, three of the most powerful AI companies in the world made decisions that will define how this technology is used — and who controls it. Anthropic refused a Pentagon ultimatum, got blacklisted by the Trump administration, and watched Claude climb to number one on the App Store. OpenAI signed a military deal hours after its CEO publicly aligned with Anthropic's position, triggering backlash from users and from inside the company. And Palantir, which has never been conflicted about its government work, was formally locked in as the AI backbone of the US military — a platform already running targeting operations in active strikes against Iran. Joel and Stephen dig into the decisions, the fallout, and what an open-source project from Austria has to do with all of it.
