  • Decoder Ring | The Red String Board Conspiracy

    Decoder Ring | The Red String Board Conspiracy
    Sep 8 2025
    There's a ubiquitous prop in just about every police procedural and conspiracy thriller: a cork board pinned with documents, newspaper clippings, and Polaroid photos, all connected by a web of red string. They go by many names, including pin boards, string boards, evidence boards, investigation walls, conspiracy walls, and walls of crazy. These boards can be vehicles of insight or manifestations of madness – and in many cases, both. But where did they come from? And can they really solve a crime? In this episode, we try to unwind the red string board all the way to its center. To aide in our investigation, we enlist the help of Aki Peritz, a former CIA analyst and the author of Disruption: Inside the Largest Counterterrorism Investigation in History. You'll also hear from Shawn Gilmore, editor of The Vault of Culture and creator of the Narrative String Theory project; and Dr. Anne Ganzert, author of Serial Pinboarding in Contemporary Television. And we learn about the intricacies of building a string board from production designers Michael Scott Cobb (It's Always Sunny in Philadelphia) and John D. Kretschmer (Homeland).

  • Astral Codex Ten Podcast | Your Review: Alpha School

    Astral Codex Ten Podcast | Your Review: Alpha School
    Jul 11 2025
    This is one of the finalists in the 2025 review contest, written by an ACX reader who will remain anonymous until after voting is done. I'll be posting about one of these a week for several months. When you've read them all, I'll ask you to vote for a favorite, so remember which ones you liked. Just as we don't accept students using AI to write their essays, we will not accept districts using AI to supplant the critical role of teachers. – Arthur Steinberg, American Federation of Teachers-PA, reacting to Alpha's cyber-charter bid, January 2025. In January 2025, the charter school application of Unbound Academy, a subsidiary of 2 Hour Learning, Inc, lit up the education press: two hours of AI-powered academics, 2.6x learning velocity, and zero teachers. Sympathetic reporters repeated the slogans; union leaders reached for pitchforks; Reddit muttered another rich-kid scam. More sophisticated critics dismissed the pitch as selective data from expensive private schools. But there is nowhere on the internet that provides a detailed, non-partisan, description of what the 2 hour learning program actually is, let alone an objective third party analysis to back up its claims.

  • Conversations With Tyler | Stephen Kotkin on Stalin, Power, and the Art of Biography

    Conversations With Tyler | Stephen Kotkin on Stalin, Power, and the Art of Biography
    Mar 24 2025
    In his landmark multi-volume biography of Stalin, Stephen Kotkin shows how totalitarian power worked not just through terror from above, but through millions of everyday decisions from below. Currently a senior fellow at the Hoover Institution after 33 years at Princeton, Kotkin brings both deep archival work and personal experience to his understanding of Soviet life, having lived in Magnitogorsk during the 1980s and seen firsthand how power operates in closed societies. Tyler sat down with Stephen to discuss the state of Russian Buddhism today, how shamanism persists in modern Siberia, whether Siberia might ever break away from Russia, what happened to the science city Akademgorodok, why Soviet obsession with cybernetics wasn't just a mistake, what life was really like in 1980s Magnitogorsk, how modernist urban planning failed there, why Prokofiev returned to the USSR in 1936, what Stalin actually understood about artistic genius, how Stalin's Georgian background influenced him (or not), what Michel Foucault taught him about power, why he risked his tenure case to study Japanese, how his wife's work as a curator opened his eyes to Korean folk art, how he's progressing on the next Stalin volume, and much more.

  • Ezra Klein Show | The Government Knows AGI is Coming

    Ezra Klein Show | The Government Knows AGI is Coming
    Mar 8 2025
    Artificial general intelligence — an A.I. system that can beat humans at almost any cognitive task — is arriving in just a couple of years. That’s what people tell me — people who work in A.I. labs, researchers who follow their work, former White House officials. A lot of these people have been calling me over the last couple of months trying to convey the urgency. This is coming during President Trump’s term, they tell me. We’re not ready.One of the people who reached out to me was Ben Buchanan, the top adviser on A.I. in the Biden White House. And I thought it would be interesting to have him on the show for a couple reasons: He’s not connected to an A.I. lab, and he was at the nerve center of policymaking on A.I. for years. So what does he see coming? What keeps him up at night? And what does he think the Trump administration needs to do to get ready for the AGI — or something like AGI — he believes is right on the horizon?
