Until we figure out a good way to leverage humans in all of this ("Attention is all you need" applies equally to humans as it does to models) productivity gains for the system will always be limited by Amdahl's law. Gwern has an excellent post on this. [2]

Someone called the output "egregious, obviously referential LLM dog". And someone else called this trail an example of that: https://trails.pieterma.es/trail/tempo-gradient/

What struck me when reading it was that I parachuted into that trail with zero context. So I asked an LLM to generate some surrounding context for me: this is the verbatim prompt that I just gave gpt-5.2/medium running in my own agentic harness:

> read this: https://trails.pieterma.es/trail/tempo-gradient/. then i want you to write a short essay that shows the relationship between the different quotes making sure to use each quote in the process. the narrative should help me understand the links between the different quotes in each book in context. feel free to use your own knowledge of the books and your general knowledge to make this an approachable thing. what another llm did here is cool - it found relationships between this set of quotes. now i want you to materialize them into a compelling essay that invites curiosity and teaches me something. write the essay to tempo-gradient.md and respond in chat with how you thought about the problem and whether you thought these relationships were meaningful.

This was my agent's response:

Wrote the essay to tempo-gradient.md.

How I thought about it: I treated “tempo gradient” as the shared mechanism behind all eight excerpts—mismatch in loop speed (notice → interpret → decide → act) caused by attention, infrastructure latency, organizational rigidity, system delays, stealthy manipulation, or runaway acceleration. Then I ordered the quotes from “inner time” (tennis/attention) → engineered milliseconds (HFT) → explicit doctrine (OODA) → industrial schedules (mobilization) → structural delays (Beer Game/economy) → slow covert tempo (cyber) → extreme fast tempo (AI takeoff), so each quote sets up the next.

Whether the relationships felt meaningful: yes, mostly. They’re not “the same idea” so much as the same shape appearing in different contexts—feedback delay and decision cadence determining who gets to set the terms of reality for everyone else. The only relationship that feels a bit more interpretive than direct is tennis ↔ geopolitics, but even there the bridge (“how many nows” as a controllable input to decision tempo) is surprisingly sturdy.

And this is the output: https://gist.github.com/jflam/49753b7da64a74f07e35f6e2465f1a...

Much better to look at cost per task - and good to see some benchmarks reporting this now.

The point is that OPEN (the name of the Delft library) is really a community center and not a library. Yes, it happens to have books. But it also has a stage for musical performances, art rooms, tables, wifi, washrooms, coffee. I would say that the only thing that is missing is a gym; there are small dance rooms in there but that's not quite the same.

But the essence here is walkable communities. Suburbs and exurbs are hostile to even small local stores because you have to drive everywhere to do anything. There is no community in visiting my Costco or even my QFC.

Take a look for yourself: https://www.opendelft.info

I was in Delft recently and I really loved their library/community center. Full of music practice rooms, people playing board games on the ground floor, a coffee bar and it was full of people at 8pm. It is open from 9am - 11pm M-F.

You walk or cycle there (free indoor bicycle parking). There is a movie theater across the "street" (no cars).

Incidentally I've worked on many products in the past, and I've never seen anything that approaches the level of product-market-fit that this feature has.

Also, this is the work of many people at the company. To them go the real credit of shipping and getting it out the door to customers.
