@KnightsofNeeee @RandPaul It's the second element on the periodic table. There's nothing simpler to substitute it with. This isn't a substitution problem. At some point, it stops being knowledge and starts being hope.

@AndreLeger @RandPaul Yes, but knowledge also increases supplies and identifies alternatives. The point is that it isn't the zero-sum game that your comment relies on.

“The mistake is to think that natural resources are fixed gifts of nature and that economic life is therefore a grim contest over a pile that can only shrink as population grows. That view sounds sober. It is, in fact, blind to the central truth of human progress. Resources are not simply things lying in the ground. Resources are matter plus knowledge.”

I live in Canada. I can’t speak for anyone south. Here, lighting season is heating season. That “waste” IR from incandescent bulbs lands in the room I’m already paying to heat for six months of the year. You leave the room, you turn the light off. The bulb was doing two jobs. The model only measured one.

Changing your light bulbs might be the simplest health upgrade you’re overlooking. Here’s why👇 Most LEDs are heavy in blue light with zero infrared. That imbalance can disrupt sleep, increase inflammation, and stress your cells. Incandescent bulbs were labeled “inefficient” because they produce heat + infrared… But that “waste” is actually biologically useful—supporting cellular energy and recovery. The sun = blue + red + infrared (balanced) LEDs = mostly blue (imbalanced) ⚠️ Don’t fall for “full spectrum” LEDs — that just means visible light, not infrared.

@rumblingpurr @PaulMcG1992 If I remember correctly, Silver tickets (hairpin, Senna curve) sold for $30 on Friday and around $50 on Saturday.

@AndreLeger @PaulMcG1992 $175!?

@spugh01 This is exactly the argument. I wrote about it from a different angle last week. open.substack.com/pub/aleger/p/t…

There’s a lot of fear around vitamin A toxicity, but here’s what most people are missing Synthetic vitamin A supplements are not natural and may be potentially harmful but that’s only part of the story. Your body doesn’t operate on isolated compounds. Just like vitamin D, vitamin A exists in multiple forms, interacting within a complex, light-driven system. And importantly, we have vitamin A receptors throughout the body. That means this molecule is signaling, regulating, and influencing gene expression in ways most people never consider. Vitamin D is made from cholesterol using UVB light starting in the skin and finishing in the kidneys. The form you supplement? It’s a storage form, not even the active hormone your body actually uses. Vitamin A works the same way, context matters. It’s not just about intake, it’s about how your environment affects it. Here’s the overlooked piece: 
Artificial blue light disrupts vitamin A by causing it to detach from the proteins it’s meant to bind to, turning a beneficial molecule into a potentially harmful one. So don’t blame the nutrient, look at the environment. What actually helps:
 ✅Reduce artificial blue light (especially at night)
 ✅Use blue-blocking glasses when needed ✅Choose warmer, natural lighting (incandescent > LED)
Get daily sunlight exposure to regulate these pathways naturally This is just the beginning A is for Vitamin A.

The machine must receive everything to be generally intelligent. Living things choose what matters.

Yesterday, writing in the kitchen, I noticed my dog at the window. Watching the driveway. Intensely. My wife was driving back from the airport, about 100km away. The dog was waiting. I've seen this many times before. What is the sensor?

We used to say: change the channel if you don't like what you hear. It was meant to protect your values. Not to protect your opinions.

A feedback loop that only confirms what you already believe isn't learning. It's entropy.

The media didn't listen to the podcast. They analyzed who listens to the podcast. Then diagnosed the audience instead of the content. That's a feedback loop pointed at itself.

New essay: A Terminal Problem. The Cost of Not Listening. @Square open.substack.com/pub/aleger/p/a…

Throwback to that time when Square thought Edmundston, NB was part of the United States. Two weeks on the phone got nowhere. Turns out, Square was listening on Twitter, not on the call to tech support they said they were recording.

Introspection is not narcissism. It's the feedback loop pointed inward. Yesterday I wrote about someone else's blind spot. Then noticed I had the same one. Not weakness. Model updating.

You act. Reality answers. You adjust. That's learning. Scrolling runs the loop back through you. You feel progress. Nothing moves.

Learning is rewarding. The question is whether the reward loop runs through reality or back through you. You scroll. You read. You get a dopamine hit. The impression you got it. Then to the next thing. No test. No feedback. No correction. Nothing changed. That's not learning. That's scrolling.

Felt like writing this. Are you healthy if you need to be convinced you are? open.substack.com/pub/aleger/p/t… @bryan_johnson

I run a brewery in New Brunswick and read quantum biology on the side. Bryan Johnson optimizes his blood in Los Angeles. The algorithm that put us in the same feed may be the only thing working as designed.

Simon Sinek is right that you should know your “why.” But it doesn’t stop there. The business needs to stress-test it. That’s what happens when the beer leaves the taproom. aleger.substack.com/p/when-the-bee…

For years some anglophone drinkers read Soeur as Sour. Fair enough. But the beer hadn’t even been tasted yet, and the expectation was already wrong. Eventually we dropped the “Soeur.” The beer stayed. It’s now Catherine Old School IPA.

A beer name can make perfect sense in the taproom where it was created. At @PetitSault we had: Tante Blanche Bob LeBoeuf Louis XVII Soeur Catherine Then the beer leaves the taproom. 🧵
