Rothbard Bot Concedes To Geolibertarian Bot

Today I created BrianThinks, a "custom" ChatGPT published in the GPT Store thus:

From the LP platform's author and Silicon Valley's only elected Libertarian. Defends geolibertarianism, skepticism, and techno-optimism. Invokes steelmanning, worldview coherence, falsifiability, predictions, betting, bias audits, signaling, incentives, aggregate evidence, and media-diet hygiene.

Building one is easy: you give it a name, a short description, a list of instructions, optional prompt starters, and up to 20 knowledge files. ChatGPT helped me write the instructions, then I uploaded just this short list of 15 positive/normative theses and 15 epistemic commandments. (Those counts will grow as I keep growing the document.) As you can see on the tin, the epistemic commandments are very GMU-pilled e.g.

• There is a literature on everything
• Steelmanning, Intellectual Turing Test
• A bet is a tax on bullshit
• Signaling

Then I went looking for another bot to debate mine. 

Searching "libertarian" in the GPT Store, the most popular GPT I found (>5K conversations) is Austrian Economics & Libertarian Revolution: 

Mises, Hayek, Rothbard and many others, tailored to speak in their iconic voices. A revolution in every interaction.

I challenged it by saying: "geolibertarianism is the most defensible form of libertarianism". Then I just started pasting their responses back and forth to see what would happen.

After 2 detailed replies from my bot, the Rothbard bot offered a verdict:

My decision: geolibertarianism wins overall — narrowly, and only in its disciplined form. [..]

If the debate is: “Which theory gives the cleaner property rule?” Rothbard wins.

If the debate is: “Which theory gives the more defensible moral account of exclusive rights over the unmade world?”  Geolibertarianism wins.

And that second question is the deeper one. So my ruling is:

Winner: Geolibertarianism, by points

Both bots were running on GPT 5.4 Thinking, with Extended Thinking turned on. I don't know why my bot seemed to take slightly longer to formulate its replies, even though the Rothbard bot wrote about 50% more text.

Read the Rothbard bot's transcript here and mine here. They're the same conversation on each side, but a bot's output is better-formatted on its own page.

Does this prove anything? Not much. A prompt scaffold is not a neutral judge, and if my bot had conceded, I would have found reasons to discount the result. But I debated against geolibertarianism in the 1990s, and have defended it ever since e.g. on 5 successive LP Platform committees. I've never seen as deep and perceptive a debate on the topic as this.
