I went to the Tour de France last week and it feels like a perfect microcosm of how Capitalism and Socialism differ (and why America is diverging economically and stagnating socially).

As an American I couldn't believe how poorly they monetized the event. You have millions of people watching and 99% of them watch for free.

The result - the median rider in the event is earning $250K a year, but the public has an event that is loved and accessible by all. The broader result is you don't get the private (and public) investment that coincides with such events in the USA because it's not being monetized well. That is, the teams earn less, the riders earn less and municipalities hosting earn less. So the aggregate result is everyone is poorer, on average, in the long-run because they don't capture the economic value of the event well.

BUT, the Europeans love their bikes. Boy do they love their bikes. And you see the happiness and social value of making this a public good instead of a private profit maximizing endeavor. So there's social value in NOT monetizing the event that **arguably** makes it a better overall social value than the Capitalist model.

In short, the American model creates a wealthier, more capitalized industry, while the European model sacrifices financial maximization to generate a widely distributed, unpriced public good. Which is better? Most certainly a mix. The hard part is getting the balance right.

بفيلم #TheOdyssey في مشهد الحوريات انقالت اقوى جملة سمعتها بحياتي ومن يومها وانا افكر فيها، عميقة بشكل خيالي

أوديسيوس يربط نفسه بساري السفينة عشان يسمع أغنية حوريات البحر (السيرينات)، الأغنية اللي محد سمعها وطلع منها حي. واحد من البحارة سأله: "شلون كانت؟" فرد عليه:

"All the things you wanted to be, and then all the things you wished you never wished for. It was a delicious itch you want to scratch, but you find it under the skin, and you can't reach it. So the delicious itch becomes unbearable. It told you what you most want is what you most can't have, and what you most can't have is what you already had and lost."

"كل الأشياء اللي كنت تتمنى تصير … وبعدين كل الأشياء اللي تمنيت إنك ما تمنيتها أصلًا. كانت مثل حكة لذيذة تبي تحكها، بس تكتشف إنها تحت الجلد، وما تقدر توصل لها. ومع الوقت، هالحكة اللذيذة تصير عذاب. كانت تقول لك إن أكثر شي تبيه هو الشي اللي مستحيل تحصله، وإن أكثر شي مستحيل تحصله … هو الشي اللي كان عندك وخسرته."

بمعنى اخر هي ذاك الصوت اللي داخل راسك، اللي يقنعك إن الحياة اللي ما عشتها كانت أحسن من الحياة اللي عايشها الحين. الصوت اللي يهمس لك:
"لو إني اخترت قرار غير … لو إني ما تركت هالعلاقة… لو إني كملت…الخ" ويخليك تدريجيًا تغيب عن واقعك

وأعتقد هذا السبب اللي يخلي اللي يسمعها ما يعيش، مو لأنها تقتل الجسد، لكن لأنها تسرق حضورك

إذا طول عمرك تتحسر على حياة ما عشتها، مستحيل تعيش الحياة اللي فعلًا عندك بكل تفاصيلها

The Man Who Gave Away Patagonia
Doug Tompkins sold his stake in The North Face for $50,000. 

He used the money to co-found Esprit. Then he sold that too, and did something almost no one does with a fortune: he disappeared.

He moved to the tip of South America in 1990 with a theory most businessmen would find absurd.

He believed the best thing a rich man could do was buy wilderness before someone else destroyed it, then hand it back to the country it belonged to.

Together with his wife Kris, a former CEO of Patagonia clothing, they bought and conserved more than 2 million acres across Chile and Argentina. For context: that is roughly the size of Connecticut and Rhode Island combined. Most of it had been degraded farmland. Overgrazed, stripped, exhausted.

The Valle Chacabuco ranch alone had been one of South America’s largest sheep operations. They bought it in 2004 for $10 million, then spent another $55 million over 20 years restoring the grasslands. 

Pumas returned. Guanacos returned. The land remembered what it was.

The Chileans were not immediately grateful. Many locals saw it as a land grab. An American buying millions of acres and telling them to change their way of life. Some accused him of planning to split the country in two. Others claimed he was building a nuclear waste site. He kept buying land anyway.

The deal his wife finalized in his name after his death became the largest-ever private land donation to a country.

Over 1 million acres handed directly to Chile, triggering government protections on another 9 million. Five new national parks. Three expanded. A conservation corridor stretching 1,250 miles.

He died on December 8, 2015, in a kayaking accident on a Patagonian lake, surrounded by friends including Yvon Chouinard. He had called what he was doing “paying rent for his time on the planet.”

There is a certain kind of person who builds something great and then builds something greater by walking away from it.

Tompkins is the rarest version: he walked away from two fortunes, bought a wilderness, and gave it to strangers.

The land is still there. The sheep are gone.

If this kind of story is what you read on weekends, you might belong here.

NVIDIA CEO Jensen Huang just said the quiet part out loud about what the education system will never admit.

For a century, we built humans to think like calculators.

The algorithm made that skillset obsolete overnight.

Huang: “The definition of smart is somebody who’s intelligent, solve problems, technical. But I find that that’s a commodity. And we’re about to prove that artificial intelligence is able to handle that part easiest.”

Software engineering was supposed to be the safe play.

Superintelligence cleared it first.

The SAT was supposed to measure intelligence. It was measuring the ability to follow instructions. Raw technical processing isn’t a competitive edge anymore. It’s the floor the machine stepped over before you woke up.

The question isn’t what you can calculate.

It’s what you can see before the data shows up.

Huang: “People who are able to see around corners are truly, truly smart. And their value is incredible. To be able to preempt problems before they show up, just because you feel the vibe.”

That vibe isn’t magic.

It’s the collision of first principles, human empathy, and lived experience no model can fake.

Huang: “That vibe came from a combination of data, analysis, first principle, life experience, wisdom, sensing other people.”

The operators who see around corners will command the AI.

The ones waiting for dashboards to update will be replaced by it.

Huang: “I think long term the definition of smart is someone who sits at that intersection of being technically astute, but human empathy and having the ability to infer the unspoken, around the corners, the unknowables.”

The unspoken variables are the new leverage.

The human psychology inside a market. The invisible friction in a negotiation. The instinct to build something nobody asked for yet.

You can’t spreadsheet your way there. You can’t prompt your way to that perception. It comes from decades of watching what doesn’t show up in the metrics.

Huang: “And that person might actually score horribly on the SAT.”

The future doesn’t belong to people who memorized answers.

It belongs to people who sense the questions before anyone thinks to ask.

The old system tested your ability to follow orders. The new one tests your ability to move through the unknown. And the machine can’t help you with that part.

That part is entirely on you.

[Kekius Maximus @Kekius_Sage]

You’ve smelled this your entire life and it was never the rain.

The smell of rain isn’t rain. It’s a molecule called geosmin, produced by soil bacteria. Humans can detect it at just 5 parts per trillion, thousands of times more sensitive than most smells.

When raindrops hit dry soil, they launch microscopic aerosols carrying geosmin into the air, like invisible champagne bubbles.

Scientists think this sensitivity helped early humans find water.

Even camels use it to navigate deserts from miles away.

That “earth after rain” smell is survival, written in chemistry.

Most people will read this and think optimists live longer because they eat better and exercise more. The study says something wilder.

Lee et al. controlled for smoking, diet, exercise, alcohol, depression, BMI, and socioeconomic status. The longevity effect still held. The most optimistic quartile lived 11 to 15% longer and had 1.5 to 1.7x odds of reaching 85 even after removing every behavioral difference.

Which means something is happening at the level of biology, not just habits.

Rozanski’s meta-analysis across 229,391 participants found optimists carry 35% lower cardiovascular event risk. Blackburn’s Nobel Prize-winning lab at UCSF found pessimistic attitudes are associated with accelerated telomere shortening. Cortisol suppresses telomerase, the enzyme that rebuilds the protective caps on your chromosomes. So chronic negative expectation literally erodes the structures that keep your cells from aging.

The loop runs: pessimistic cognitive style → sustained HPA axis activation → elevated cortisol → telomere degradation → accelerated cellular senescence. Optimists interrupt that loop at the top. They show less emotional reactivity to stressors, faster recovery from acute stress, and they default to reframing threats as challenges rather than catastrophizing.

The part nobody talks about from this paper: the authors explicitly state optimism is modifiable. This isn’t a personality trait you’re born with. Cognitive reappraisal training, morning sunlight for cortisol rhythm regulation, deliberate breathing protocols for vagal tone, structured gratitude practices. All of these shift the prefrontal cortex patterns that determine where you sit on the optimism spectrum.

A 35% reduction in cardiac events from a trainable psychological variable is a bigger effect size than most supplements on the market. That’s the real story buried in this abstract.

I recently spoke to a marketer who ran a $40M brand with just two designers and ONE AI process:

He gave me and my team a masterclass on using AI to scale marketing and creative.

He chains 7 different tools together for: ideation, image creation, video editing, and iterating based on performance.

I paid him 6-figures to build these systems for my companies.

Now, I’m giving them away for free.

[Rock Chartrand @RockChartrand]

Capitalism’s greatest problem isn’t that it leaves people behind.
It’s that it lifts so many ahead that envy replaces gratitude, and people start thinking wealth just falls from the sky.
