“Every Tuesday night for the rest of my life, I'm going to remember that, oh, it's 9 o'clock PM Eastern time, I got to be on show and on live with John right now. The conversations we had, the laughs we had, the debates, and that familiar voice are things that I'm gonna miss more than words.”
Episode 811 of DH Unplugged, titled Remembering JCD, published July 28, 2026, is a heartfelt tribute to co-host John C. Dvorak, who passed away peacefully at home the previous week while watching NCIS with his wife Mimi. Host Andrew Horowitz is joined by John's son, JC Dvorak, to reflect on 18-plus years of partnership behind the microphone, share family stories, and announce a public memorial meetup.

“Every Tuesday night for the rest of my life, I'm going to remember that, oh, it's 9 o'clock PM Eastern time, I got to be on show and on live with John right now. The conversations we had, the laughs we had, the debates, and that familiar voice are things that I'm gonna miss more than words.”
- Andrew's on-air tribute to John and readings of condolence notes from listeners worldwide.
- JC Dvorak on growing up around figures like Larry Ellison, Kai Power Tools, and early CNET tech coverage.
- Nvidia's $250 billion OpenAI backstop, the Ohio data center buildout, and circular AI financing.
- Semiconductors entering a bear market, SK Hynix earnings, and the CXMT IPO surge in China.
- OpenAI's reported rogue model incident involving Hugging Face and the sandbox debate.
The tone is by turns tender and unflinching. Reflecting on the loss, Horowitz says:
He made our audiences smarter, and friendships richer. And Tuesday nights are never going to be the same, ever.
JC Dvorak captures the family's private ritual, recalling standing weekly dinners: "For the past, you know, decade or more, we've been doing a dinner every Friday, and last Friday was really hard because it was, you know, we didn't have dinner." The hosts also confirm an in-person tribute and No Agenda / DH Unplugged meetup in Fort Lauderdale on 8/8 at 3:33 PM, coinciding with John's funeral earlier that day.
On the market side, the discussion drills into what Horowitz calls a "rug pull" mood around SpaceX, Tesla robotaxi promises, and the Cathie Wood trillion-dollar thesis. The pair unpack a chart posted at dhunplugged.com showing Nvidia at the center of a circular financing loop involving Oracle, SoftBank, and major banks, drawing parallels to Lucent and Nortel's vendor financing during the 1999 to 2000 telecom bubble. JC Dvorak, speaking from inside the AI industry, details how DeepSeek and Moonshot's Kimi K3 are pressuring margins, describes a client migration from a $10 million Anthropic contract to a $100,000 on-prem Kimi deployment, and questions whether OpenAI's incident was incompetence dressed up as existential marketing. The Close to the Pin winner: Mark Pugner of Ireland, using John's old pseudonym, guessed SpaceX at $133 against a $123.99 close.

Frequently Asked Questions
- What happened to John C. Dvorak, and when is the public memorial?
- John C. Dvorak passed away peacefully at home the week before Episode 811 aired, while watching NCIS on the couch with his wife Mimi. He had recovered from earlier heart trouble and was reportedly doing well, so the death caught family and colleagues by surprise. A No Agenda / DH Unplugged meetup and tribute is set for 8/8/2026 at 3:33 PM in Fort Lauderdale.
- Who is JC Dvorak, and what perspective does he bring to Episode 811?
- JC Dvorak is John's son and a software professional working inside the AI industry. On the episode he shares childhood memories of dinners with figures like Larry Ellison, playing with early tools such as Kai Power Tools and Bryce 3D, and hand-me-down Macs. He also offers technical analysis of language model economics, margins, and sandboxing practices.
- Why are Andrew Horowitz and JC Dvorak concerned about circular AI financing?
- They point to a chart posted at dhunplugged.com showing Nvidia at the center of a loop involving Oracle, SoftBank, and major banks, with Nvidia backstopping $250 billion for OpenAI and Ohio data center buildouts potentially costing $500 billion. JC compares the setup to Lucent and Nortel's vendor financing during the 1999–2000 telecom bubble, which ended badly.
- What does JC Dvorak say about Chinese AI models pressuring US margins?
- He explains that DeepSeek disclosed north of 90% per-token margins, and Moonshot's Kimi K3 rivals Anthropic's Opus at a fraction of the cost. He cites a client that migrated from a $10 million-a-year Anthropic API contract to a roughly $100,000 on-prem Kimi deployment running on their own B100 hardware, illustrating the erosion facing US closed-weight providers.
- How do the hosts frame the reported OpenAI 'rogue' model incident involving Hugging Face?
- JC Dvorak argues it looks more like sloppy engineering than an emergent Terminator moment, noting that Moonshot's Kimi K3 paper devotes two pages to proper sandboxing using off-the-shelf tools like Firecracker VMs. He suggests OpenAI and Anthropic benefit from the scary narrative because regulation and existential fear help protect their high token margins from open-weight competition.
- Who won the Close to the Pin contest for SpaceX, and what was notable about it?
- Mark Pugner of Ireland won with a guess of $133 against SpaceX's actual close of $123.99, coming within 7.33%. The name is a pseudonym John C. Dvorak himself used for years in his writings, which Andrew Horowitz only recognized after the winner emailed him back. Marcus G. of Thatch House in England finished second at 8.72%.
