In 1969, Milton Friedman proposed what became known as the "Friedman Rule" - a monetary policy where nominal interest rates should be set to zero, eliminating the opportunity cost of holding money and optimizing monetary efficiency. 🧵 1/15

String theory is probably a field that has set back quant trading by at least 10 years. Stealing top tier trading talent to do make believe 26 dimensional geometry, inflate boomer professors’s grant budget, and produce zero testable hypotheses or applications after 50 years

We freaking knew it. We called it.

Four different fields independently arrived at roughly the same picture:

Mathematics → attractors

Cognitive science → attractor networks

Linguistics → conceptual spaces

AI → activation geometry

Maybe the interesting question isn’t whether these systems are the same.

Maybe it’s why they keep converging on the same geometric language.

@jawwwn_ @60Minutes I didn’t “think I was qualified”. There was no other choice. No one good would join a rocket startup as chief engineer that they thought was destined for failure.

this is just the most ridiculous AI application i've ever seen lol

a Peter Thiel-backed startup that makes AI collars for cows is now worth $2 billion

and the more I read about it the cooler it gets. here's how it works:

every cow wears a solar-powered collar that talks to a network of radio towers and an app on the farmer's phone

instead of building physical fences, the farmer draws the fence on a map in the app, and the collar keeps each cow inside that invisible line using GPS

when a cow drifts toward the edge, the collar plays a sound to steer her, and a gentle vibration tells her which way to go.

it's like how a car beeps as you back up toward a wall

the cows learn the cues in a few days

so now a rancher can move an entire herd to fresh grass by sliding the fence on a map, without driving out to open a single gate

and that same collar is reading each cow's body the whole time.

it takes five readings per second on every animal, so the AI can catch a cow that's sick, injured, ready to breed, or about to give birth before a person would ever notice walking the field

so it's basically like WHOOP for cows too lol

and they gave the AI behind it the perfect name: the Cowgorithm

it's been trained on more than 7 billion hours of real cow behavior, which is why Halter calls the data its real asset and moat.

they know what a normal cow looks like better than anyone, so they can flag the odd one out instantly

it's already on more than 1M cattle across New Zealand, Australia, and a bunch of US states.

California even used it on public land to graze cattle in patterns that clear dry brush and slow down wildfires

costs about $5 to $8 per cow per month

a job that used to mean barbed wire, gates, and driving the fields all day is now mostly 1 person on their phone

Pope Leo XIV was expected to reflect on pressing social issues and to refer - in his addresses to the Spanish society - to his groundbreaking "Magnifica Humanitas" encyclical.
He did not disappoint.
If you need Pope Leo's "Magnifica Humanitas" soundbite, here it comes:
" We must avoid humiliating or antagonistic words, opting rather for a clarity that sheds light and a frankness that unlocks new possibilities.
We cannot condone naïve enthusiasms, nor fuel unfounded fears. Instead, let us establish standards for discernment -- the dignity of the human person, the universal destination of goods, the preferential option for the poor, care for our common home and peace -- and let us translate these standards into practices such as responsible planning, the assessment of human and social impact, the inclusion of the most vulnerable, the promotion of digital literacy and guiding research and industry toward justice and peace."
(Magnifica Humanitas, 14).

Hot take: Universities charge $300,000 for a degree that teaches you skills any LLM can do for free. At some point we need to have an honest conversation about whether higher education is the greatest individuals misallocation of capital in recent history.

Now we know why Peter Thiel packed his bags for Argentina.

Milei just submitted his AI legislative framework to Congress, where he proposes:
- zero regulation on AI development,
- a brand-new "non-human corporation" category for AI/robot-operated entities with limited liability
-a low-tax regime with flexible governance rules.

The Dutch East India Company gave the world the limited liability company in 1602. Milei wants Argentina to do the same for autonomous AI agents in 2026.

BREAKING:

Liberal Bill C-9 has passed the Senate with an amendment. The vote was:

YEA: 45
NAY: 13
ABSTAIN: 2

35 were absent for the vote.

Because of the amendment (adding the noose to the list of criminalized hate symbols), Bill C-9 will be sent back to House of Commons.

🚨 PRESIDENT TRUMP DROPS BOMBSHELL ON CUBA:

“Cuba has collapsed. We will handle that as soon as we take care of the Islamic Republic of Iran… then on our way back, we’ll make a little brief stop.”

Trump says 95% of Cubans voted for him, and he’s not forgetting them.

“These are unbelievable people. Energetic. Entrepreneurial. Some of the richest people in Miami are Cuban. We will take good care of them. We will let them go back to their land, invest in Cuba, and be with their families. We have very good plans.”

NEXT STOP, CUBA.

One of Lee Kuan Yew’s most consequential decisions was to keep Common Law out of sheer pragmatism. It forces political discipline and restraint, and restraint is what persuades the world's capital to come pouring in and stay.

Starlink V3 satellites have >10X bandwidth of V2 and there’ll be >10X launched, which means >100X more bandwidth.

Also, altitude will be 350km vs 550km, so min latency can be cut in half.

Light travels 300km/ms in space, so physics round trip min latency drops to <5ms.
