Unlimited inflation
Hey @Jon Underwood is this new Fed Chair promising unlimited inflation? For me his math isn’t mathing. I keep hearing austerity out of one side of this mouth and rising inflation out of the other. Of course you know I think that finance will s black magic, but we are both concerned about inflation surely. Do you have any idea what’s happening?

The Lesson of the Sandwich Board
Younger Skool members may not believe it but, at the weekends around town when I was young, there would often be someone walking around carrying a sandwich-board-frame on their shoulders with the message, written in big, bold letters “Repent - for the End is Nigh”. Of course, the intent was a religious one. A recent article makes me wonder if any Californians are soon going to be doing likewise, carrying the same message but with a different interpretation and target attached to the word “Repent”. California is set to experience climate change in big, bold reality. See - https://www.theguardian.com/us-news/2026/apr/01/snowmelt-american-west

I got a handwritten letter last week from a neighbor with a similar sentiment. She’s a member of the local Jehovas Witnesses. Usually, she and I share news and gossip about the neighborhood. I like talking with her about the Jubilee. But something has changed in her—she sent me a very stark warning. I think most of us feel it.

@Alwyn Lewis I can’t blame Trump for all of our problems. It took a lot of bipartisanship to get here. Democrats are still defending the Clintons, the Bidens…and they even defend the Bushes. I think we’ll run out of critical minerals before they stop the War Machine.
Promoting Advanced Artificial Intelligence Innovation and Security, Executive Orders, June 2, 2026
This document (see: https://www.whitehouse.gov/presidential-actions/2026/06/promoting-advanced-artificial-intelligence-innovation-and-security/) goes to great effort to say what it is not: ”Sec. 3. Secure Frontier Model Deployment... (c) Nothing in this section shall be construed to authorize the creation of a mandatory governmental licensing, preclearance, or permitting requirement for the development, publication, release, or distribution of new AI models, including frontier models.” Apparently zero regulation—perhaps the fear of regulation or the fear of being told ”no”—is too much regulation for AI in Trump’s America. This new category of AI models designated as ”covered frontier models”, is a completely secret process with zero transparency. The War Machine is now drafting AI models instead of soldiers. And why put Treasury and Commerce in a national security loop when their actual tools (such as standards and public reporting) are transparent by design?

Beyond the Pacioli group: how to apply category theory to thermodynamics
So, I figured out that the symmetry in DEB satisfies the first law of thermodynamics. I’m still curious about the second law, so I’m working on applying Godley tables to this fun find: https://golem.ph.utexas.edu/category/2022/07/how_to_apply_category_theory_t.html

@Steve Leo well, I used one kind of abstract algebra (group theory, which is the abstraction of symmetry) to understand DEB. But, I feel like I need category theory to understand Godley tables. Category theory is the abstraction of composition. You see, when we abstract from the transaction level (DEB) up to the sector level (macroeconomics a la Godley), there are some flows that are not reversible (e.g., imports and exports). The fact that there are no inverses (e.g., exports and imports are irreversible) means that I can’t ”group” them with group theory. This means I need a different and more abstract kind of algebra to compose the macroeconomic circuit, hence my interest in category theory. I’m studying physics and circuit math in the fall. I figured out the DEB math for the first law of thermodynamics, and now I’m focused on the second law. I think the math is deceptively simple. It’s as perfect as Euclid’s ratios.

@Steve Leo i wonder about that too. I think there is a good chance that these methods could benefit financial analysts. It would be nice to include more math and science in the curriculum for college students. There’s a mathematician named Emily Riehl who is working on an undergraduate category theory course. I’d like to see that widely disseminated.
