It is time for the United States Postal Service to ban junk mail. Unsolicited spam calls are already prohibited by the FCC. Emails are heavily regulated by the CAN-SPAM Act of 2003. Junk mail is the majority of mail, 100 million trees per year. Enough!

We could just stick all the nuclear waste ever in a parking lot in the desert and it would be fine. Long term storage is a boogyman parroted by fucking nerds who would be against nuke for any reason.

THAT’S IT? This is what 20 years’ worth of spent nuclear fuel looks like safely stored at the former Maine Yankee nuclear plant. The plant generated 119 billion kilowatt hours of reliable power from 1972-1996, which is enough to power half a million homes each year.

You can’t get a $1 million mortgage if you make $100K/year. You can’t get a $75K car loan if you make $35K/year. The fact that you can get $250K in student loans for a college degree where you’re expected to earn $40K/year is unacceptable and a complete failure of US society. We have 18 year old kids making financial decisions that all but guarantee a lifetime of economic insecurity. These kids do not have the capacity to understand the implications of the debt they are taking on. The corrupt university system has successfully convinced them going to college is the “smart thing to do” and that it will all work out. These colleges should have to take the financial hit when they load up 18 years olds with hundreds of thousands of dollars in debt that basic math would tell you will never be repaid. The federal government backstopping all these student loans does nothing but enable colleges to jack up their prices every year with zero accountability. Shameful.

This is a good illustration of a general principle: As you build new high-end apartments, people move up, freeing up supply of lower-tier apartments. Building luxury housing thus lowers downmarket rents. You don't need to build 'affordable housing' to make housing affordable.

Here's something fascinating happening in the apartment market right now. The cheapest, oldest apartments (Class C) are getting crushed right now. But ONLY in cities that just delivered tons of new apartments. Let me show you the numbers: Denver: Class C rents down 13.9% Naples: Class C rents down 13.5% Austin: Class C rents down 13.3% Phoenix: Class C rents down 10.5% San Antonio: Class C rents down 7.2% Dallas: Class C rents down 6.5% What do all these cities have in common? They just absorbed a massive wave of new apartments. But here's the twist... In cities that DIDN'T get a big supply wave? Class C rents are actually RISING. 20 cities saw Class C rents go UP more than 3%. 19 of those 20 cities had supply BELOW the national average. So what's going on? It's basically musical chairs. When a brand new luxury apartment opens up, where do those renters come from? They don't appear out of thin air. They move from slightly older apartments. Those apartments now have vacancies. So they drop their rents to compete. That pulls in renters from even older apartments. And down the chain it goes. Eventually it hits the oldest, cheapest apartments at the bottom. And here's why they get hit the hardest: People living in Class C apartments are already spending a huge chunk of their paycheck on rent. To fill empty units, landlords have to cut prices A LOT. Sometimes enough to attract people who couldn't afford market-rate apartments before. It's like a waterfall effect. The water (new supply) at the top pushes everything down. But here's the important part: This proves that building new apartments - even "luxury" ones - reduces rents all the way down the spectrum. If it was just an affordability crisis, you'd see Class C rents falling everywhere. In high-supply cities AND low-supply cities. But we're not seeing that. We're seeing a perfect split: Lots of new apartments = falling Class C rents Few new apartments = rising Class C rents New supply at the top creates relief at the bottom. Also: wages have been growing faster than rents for 3 straight years. More people can afford apartments today than before. The bottom line? This is what happens when you actually build housing. Supply works. (Chart and analysis from Jay Parsons - one of the sharpest real estate economists out there)

This is a genuinely incredible story: China found in U.S. archives an energy source that could power its entire future for 20,000 years - and they just made it work. I'm not exaggerating. In the 1960s the U.S. - specifically Oak Ridge National Laboratory in Tennessee - invented a revolutionary type of nuclear reactor that could run on thorium instead of uranium (much more abundant and cheaper), with no meltdown risk, generating 50x less waste, and requiring no water. Then, due to messy politics, they killed the program in 1969 and fired the visionary behind it. Afterwards the declassified blueprints for the project sat forgotten in archives for decades. That is until Chinese scientists found them and decided in 2011 to run an experimental project in the Gansu desert to see if they could make it work. A few days ago, after 14 years of work, they finally did. I spent many days researching this and wrote the full story - how the technology works, the bureaucratic politics that killed it in America, and why this could genuinely be game-changing.

The key advantages of the thorium molten salt reactor are: - It can't have a meltdown - It doesn't require overpressure to work - It doesn't produce overpressure - It doesn't build up explosive gas (H2) - It is passively cooled - Most of it's waste lasts for decades instead of millennia Salt reactors have been recognized as safe for decades. Besides material challenges, other reactor types were favored mainly because of the possibility of producing weapon-grade Plutonium.

This is wild: ALL net wealth in the US stock market since 1926 has been generated by just 3.44% of companies. To put this differently, ~97% of all stocks have barely contributed to long-term shareholder wealth creation. The top 1.88% of companies reflect 90% of total gains. Interestingly, just 0.26% of firms have created HALF of all wealth. This highlights the extreme concentration of stock market returns in top-performing companies. Market wealth is heavily skewed toward a very small minority of companies.

“Just be kind.” Feminization made the West acutely better but chronically worse. For each time we favored kind lies over unkind truths, we functioned momentarily better by sparing feelings but permanently worse by weaving lies into the fabric of social reality

Everyone’s been saying psilocybin “rewires the brain.” Cool. But where, exactly? A new 2025 Nature study finally has the answer. And this could change how we treat depression. 🧵

Mike Rowe: “We’ve been telling kids for 15 years to learn to code.” “Well, AI is coming for the coders.” “It’s not coming for the welders, the plumbers, the steamfitters, the pipefitters, the HVAC, or the electricians.” “In Aspen, I sat and listened to Larry Fink say we need 500,000 electricians in the next couple of years—not hyperbole.” “The BlueForge Alliance, who oversees our maritime industrial base—that’s 15,000 individual companies who are collectively charged with building and delivering nuclear-powered subs to the Navy … calls and says, we’re having a hell of a time finding tradespeople. Can you help?” “I said, I don’t know, man … how many do you need? He says, 140,000.” “These are our submarines. Things go hypersonic, a little sideways with China, Taiwan, our aircraft carriers are no longer the point of the spear. They’re vulnerable.” “Our submarines matter, and these guys have a pinch point because they can’t find welders and electricians to get them built.” “The automotive industry needs 80,000 collision repair and technicians.” “Energy, I don’t even know what the number is, I hear 300,000, I hear 500,000.” “There is a clear and present freakout going on right now. I’ve heard from six governors in the last six months. I’ve heard from the heads of major companies.” @mikeroweworks

Japan has developed a groundbreaking nuclear innovation called the Yoroi Reactor — a microreactor no larger than a shipping container. Designed for isolated communities and disaster zones, this buried reactor provides clean energy for a full decade without refueling. Unlike traditional nuclear power plants, the Yoroi has no towers, no on-site staff, and no risk of meltdown. It uses molten salt cooling and low-enriched uranium in a sealed unit, making it safe even during earthquakes. Two Yoroi Reactors are already powering remote towns in Hokkaido, Japan, replacing dirty diesel generators with zero-emission energy. The system is completely passive — it shuts down automatically if anything goes wrong. By 2030, Japan plans to install 50 more across the country. This might be the boldest nuclear experiment the world has ever seen.
