This is what your soul needs, not Dubai.

[🕊️ @lichthauch]

Fatherhood strips the paint off every man alive, all that enduring self mythology you carved out for yourself over decades of living, that entire carefully manicured persona gone in six months because a child does not care who you think you are. a child cares what you do when you think no one is looking, and someone is always looking now. your son will learn what you are not from your words but from watching your face when his mother is talking, from how you sit when you're tired, from whether you get up anyway. and if what he finds there is weakness he will know it with the same dumb immediate certainty that an animal knows rain is coming

Every day I see something I am convinced I hallucinated.

The great lie is that society is divided between rich and poor.
The great truth, as David Friedberg puts it, is makers vs takers.

Makers build, create, and deliver real value: houses, software, art, businesses, and everything that moves civilization forward.

Takers watch, criticize, analyze, and politic. They push the lie that the rich hoard unfairly so the poor must seize it… all while positioning themselves to rule the chaos.

As @friedberg tells his kids: “At the end of the day, if you made something and someone else valued it, you were a maker. That was an amazing achievement. That is a great day.”

Takers thrive on division. Makers drive progress.

Time to choose your side.

No, you don't get it.

He does not have $1 trillion sitting in cash, it is 99% stock in his companies.

To make that wealth liquid would mean selling all that stock which would swiftly destroy *both* the companies (Tesla, SpaceX, others) and the wealth. If he sold it all, he'd end up with maybe $100b max, several hundred thousand people would be out of work, the companies ruined and many of their suppliers also ruined.

Okay, but now Elon has $100b in cash, and can "solve the world's problems".

$100b divided by the world's 8 billion people is $12

If you were in charge, several of the most innovative industrial companies in the world would be destroyed, hundreds of thousands out of work, and space would again close to human civilization for another generation.

But everyone on earth could have one nice meal and you could revel in your altruism.

All personnel are accounted for and safe. It’s too early to know the root cause but we’re already working to find it. Very rough day, but we’ll rebuild whatever needs rebuilding and get back to flying. It’s worth it.

Naval really nailed it with this one: Money < life < attention

Yeah

Warren Buffett delivers a masterclass on life and leadership here.

This is worth more than reading 90% of investing books.

Life wisdom from Charlie Munger

[HotSotin 🇫🇮🇺🇦🇪🇺△ @HotSotin]

Crazy idea: Let's split a country in socialist and capitalist halves and check in on them in 75 years.

[Investment Wisdom @InvestingCanons]

Charlie Munger:

“If you will overspend your income and be full of jealousy and resentments, you can have a lousy, unhappy life and die young. All you've got to do is learn from Mozart.”

[The Rabbit Hole @TheRabbitHole]

Capitalism creates so there’s more for everyone.

Socialism is the weaponization of greed and envy making everyone worse off.

[The ₿itcoin Therapist @TheBTCTherapist]

Last year Warren Buffet said he was worried about the long term value of the U.S. dollar due to central bank debasement.

Today the U.S. National Debt hit $39 trillion.

[Patient Investor @patientinvestor]

During the peak of the dot-com mania, a Berkshire shareholder told Buffett & Munger to “speculate” 10% into tech & software.

Their answer is a masterclass in discipline:

Energy reality check:

🇨🇦 Canada → ~6 million barrels/day
🇳🇴 Norway → ~4 million barrels/day
🇸🇦 Saudi Arabia → ~10–11 million barrels/day

Norway used its oil to build a $1.5+ trillion oil fund, which is one of the largest wealth funds on Earth.

Canada has far more resources than Norway yet we keep acting like developing our own energy sector is a problem.

Imagine how prosperous Canada could be if we treated our oil the way Norway did.

Norway treats oil like a national asset. Canada treats it like a political problem.

I had the most fun doing this deep dive.

Every color you see in a peacock's tail is a lie. The feathers contain exactly one pigment: brown. That's it. The blues, greens, and teals aren't made from any dye. They're made from structure. Each feather strand has a tiny crystal grid of melanin rods and air pockets built into it, and this grid reflects light the same way a prism splits a rainbow. Change the spacing of those rods by less than the width of a virus, and the color flips from blue to green to yellow. The margin of error for this to work is one twenty-thousandth of a millimeter.

That geometric grid in the image is real, and a 2025 study figured out how it works. A peacock grows about 170 eyespots, and that number is biologically locked in. The feathers grow from the tailbone in a zigzag pattern, adding rows of 10 or 11 each year, creating the tightest possible packing arrangement in nature. When fanned out, the eyespots form spirals that follow the same Fibonacci pattern you see in sunflowers and pinecones.

It gets wilder. The barbs inside each eyespot are hooked together like Velcro, making them heavier than the loose feathers around them. So when the peacock shakes his tail (the feathers vibrate like guitar strings), the eyespots stay perfectly still while everything around them shimmers. It's a built-in optical illusion. The shaking also produces a low hum below the range of human hearing, but the females pick it up.

Robert Hooke first noticed these structures in 1665 through one of the world's earliest microscopes. 360 years later, engineers are still trying to copy them. A UK startup called Sparxell won a major innovation prize in 2023 for making paint from plant cellulose that uses the same trick, color from structure instead of chemicals, which means it never fades. Researchers at the University of Michigan used the same idea to build screen prototypes that work like e-paper in direct sunlight.

The kicker: a 7-year study in Japan found that peahens don't actually pick mates based on how many eyespots they see. All this physics, all this precision, and the females might not even care about the math.

🚨: 'My battery is low and it's getting dark'

This was the last message sent by Opportunity Rover before losing the contact with Earth and shutting down forever after battling an extreme sand storm on Mars.

Rover was expected to survive only 90-days on Mars but it kept exploring the Red Planet for nearly 15 years.

Sent from 225 million miles from Earth, these last words will forever be remembered.
