This edition of Good Tokens is best enjoyed while listening to the Phil Collins version of You Can't Hurry Love.

Shameless Self Promotion

Introducing AgentCAD: About a month ago I became obsessed with the idea of a command line tool for creating CAD drawings as a way to empower coding agents (Claude, Codex, etc) to be better at designing 3D objects. The first version of it is here and I'd be lying if I didn't say I had a delightful time building it. Try it out by firing up your favorite coding agent, grabbing the starter prompt from here, and giving it something to design for you. You and your agent can send me feedback directly from the CLI app or email me here: hello@jdilla.xyz

Dangerously Skip Permissions: In other command line news, my friend Rami, the head of Product for Stripe's new command line product Projects.dev stopped by Dangerously Skip Permissions to talk about CLI tools and what it's like to be a PM in the age of AI. If you need any more reason to check it out, Rami is one of the 5 best PMs I've witnessed up close. Full episode is here or a taster is here.

Henrik Karlsson — How to Walk Through Walls Reminiscent of Derek Sivers's There's No Speed Limit. Henrik is really cooking right now.

The Kranz Dictum: If this one doesn't get you going, please have someone check your pulse because you might be dead.

The Creation of Instant Coffee I always love a good "how X came to be" piece. I was surprised by how many of these chemical processes I recognized from my time at Macro Oceans.

Rented Virtue The connection between culture and value creation is underrated. So are the Quakers!

We are called to be faithful, not successful. Ryan Burge preaches.

Why Are American Passenger Trains Slow? There are no solutions, only tradeoffs.

ChinaTalk's Best Books Q1 2026 is out. Always a good list to mine for your reading queue.

Things I learned

  • AI is less popular than ICE. From an NBC News March 2026 poll, via Roy Bahat's excellent "This is Not a Newsletter."

  • As an adult human, our odds of dying double every eight years.

  • There's only one European company more valuable than Home Depot, which is itself only the number-four American retail company.

  • During Pangea, whole sections of the earth went without rain for thousands of years. The megamonsoon cut off the interior from atmospheric moisture for stretches of geological time.

  • Consumers aged 55+ now drive 45.3% of all U.S. spending (Unusual Whales).

Musings

"Such is the blindness of men, that they even glory in their blindness." — Augustine

"The life of man is like a game with dice; if you don't get the throw you want, you must show your skill in making the best of the throw you get." — Terence. Literature and History continues to delight me.

"Does an idea belong to those who use it or those who find it? I've decided to think that ideas belong to those who use them, thus to everyone." — Blek le Rat. See also: you don't own the story; you do own the execution.

LLM Corner

Agentalent.ai: A marketplace where companies hire verified, human-supervised AI agents. Each agent has a human handler. It's like a staffing agency for AI. The future is weird and it's already here.

ElevenLabs Secures AI Agent Insurance: First AIUC-1-backed insurance policy covering AI voice agents. They passed 5,000+ adversarial simulations to get it. This is a big deal for enterprise adoption — insuring against hallucinations and unauthorized actions is the kind of boring infrastructure that actually unlocks deployment.

Second Opinion with Dr. Dua Hassan

2026-04-12

Second Opinion Podcast

Over the past several months, I've been collaborating with a friend of mine, Dr. Dua Hassan on her podcast.

One of the things that I think is underrated about being a parent is the degree to which medical stuff with your children just happens to you. Even the planned stuff — the 6 month and 1 year appointments — inevitably happens on a day when you're tired or distracted and there's less time, attention, and energy to get much beyond "What" and into "Why".

Which is exactly why I loved doing this podcast. In it, Dr. Dua takes the time to explain why things are the way that they are in a way that I've never had time for while raising my kids. In the process, I've learned an incredible amount, like the heroic story of Dr. Robert Guthrie, who singlehandedly willed the PKU test into existence after his niece was affected by undiagnosed PKU or that once upon a time doctors would lick babies to understand if they had certain conditions that caused their skin to be salty.

The first season is all about the first 24 hours of life and the shots, tests, and eye goop that are applied to a baby right after it's born. I've been through this three times and recognized every step — but couldn't have told you much about them until this show.

You can find it on Spotify here or on YouTube here. Send it to a parent or soon-to-be parent you love!

Craft is the Antidote to Slop — Will Manidis is in my internet top 5. I hope I'm not insulting him when I say he has great taste (link: https://minutes.substack.com/p/against-taste)

Backseat Software I am so sick of being interrupted for feedback.

Speed Can Reindustrialize America Austin Vernon is also in my internet top 5.

Fraud Investigation — Shorter patio11: Fraud is a policy choice.

Robot Soldiers Are Reporting for Duty — Armed ground robots serve a fundamentally different purpose than drones. Drones are light artillery — great at inflicting casualties. But the hard problem in warfare is holding terrain, and that's where ground robots start to matter. The Ukraine conflict is making this real fast.

Things I learned

It worked for me

Alpha-Bots — Consistently one of my kids' favorite toys. Most likely to get the 3 and 5 year old playing together for 20+ minutes at a time while I'm not in the room.

No Knead Bread — My friend Chris introduced me to this No Knead Bread recipe late last year and it has quickly become a part of my family's weekly routine. Who knew fresh bread could be this easy?

The Mundanity of Excellence. Excellence is a product of different kinds of work rather than different levels of effort. Technique (how things are done), discipline (doing things correctly, consistently), and attitude (how things are approached) are the things to focus on. “What we call talent is no more than a projected reification of particular things done: hands placed correctly in the water, turns crisply executed, a head held high rather than low in the water.”

“Those of us who retain grand ambitions and high ideals are perhaps to liable to become Casaubonnish, to become like Lydgate, so preoccupied with the dreams of youth and so stung with the perpetual sense of failure as we became assimilated to our lives, that we forgot to do the good that we can do in the time we have to do it in.” — Henry Oliver on Middlemarch

Pluto’s icy mountains..

Georgia is losing its southern drawl. One of my favorite things about attending the University of North Carolina was learning the subtle differences between North Carolina accents, to the point where I could place where you went to high school by how you spoke. They were beautiful and unique.

Musings

“Just slap something on it” — Vincent van Gogh

It should be easier to send gifts to a person having only their phone number.

“If you get mad you will be seen as losing almost-every argument, regardless of what the other person did that led to you getting mad, again excepting really extreme and explicit evidence.” — Uri. I should be forced to reread this once a month.

Things I learned

Just 13% of Gen Z believes that most people can be trusted — Ryan Burge. Surely at some point this has to rebound?

Bing Crosby’s “White Christmas” is the best selling single of all time, which I learned at a BP gas station video ad of all places and confirmed via Wikipedia.

The second fastest growing sector in America between 2019 and 2024 was gambling — Matt Stoller

In case this is the last Good Tokens of the year, have a great holiday season and end of 2025. See you in 2026!

A message from my sponsor

Christmas is just 7 days away. If you’re here, you already know about my dear friend Uri’s hit new game Person Do Thing, but out of love for the game and it’s creator, I have to say one final time, this is a perfect stocking stuffer and a great way to spend time with your friends and family without a screen. Highly recommended!

Human Invariant: “In simple terms, good work gets noticed by everybody who matters.”. On some level, I think this is a useful reduction. At the same time, I also think that HI underates the dance between creators and audiences. Most great things are to some degree co-created. Also, Human Invariant interviews a YouTube screenwriter.

On Bill Snyder’s career at Kansas State.. This level of obsession makes me wonder if I have What It Takes.

I feel I don’t spend enough time thinking about Esmerelda and how ambitious of a project it is.

The story of kelp pots (seed starter pots made from seaweed), a fun story in which I played a small part.

New to me: The Gettier Problem

The Lost Generation. This one is controversial because it deals with race and DEI, but if you can distance yourself from that a little bit, it’s really informative. It made me believe more in the Elite Overproduction Hypothesis.

The story of the fight over Romansch. Particularly enjoyable for me because the Engadin is among my favorite places in the world.

Things I learned

The average boomer will get paid out significantly more in medicare and social security than they paid in taxes — Russ Greene. Soon we’ll need a Boomer Corner.

This was the first year where no Pearl Harbor survivors were able to attend the commemoration ceremony.

Americans drive 3.3 trillion miles each year — Rohit

The EU makes more from fines on US tech companies than it does from taxes on all EU tech companies — David Fant

Lebron James has played against 35% of players in NBA history — CBS Sports. To be fair, he has played in 28% of the league’s seasons. I think this makes him the Queen Elizabeth of athletes.

Musings

I feel like the Grinch saying this, but we’ve got to cut down on the number of special clothing days (e.g., pajama day) that are happening in schools or daycares. All it does is create stress for me as a parent and I don’t get the sense that my kids actually enjoy these. Who is this for?

LLM corner

Some shameless self promotion: The latest episode of —dangerously-skip-permissions: How Penny Schiffer works. Penny is another technical product manager turned AI software developer who I think has really mastered creating with AI.

Dexter, Claude Code for researching stocks.

GenAI created ads outperform human created ads by 19%… unless they are disclosed as created by AI, in which case the performance goes down by 32% — Eric Seufert

The coming AI wildfire.

Dev Browser, a better tool for agents to view local webpages. I can’t wait to play with this one.
