⚡️AI will not replace thought.

It will expose who was never thinking.

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 used to think that the benefit of GLP-1 drugs (like Ozempic) was dependent on weight loss.
Now we know so many health benefits have little to do with that!

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.

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.

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.”

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.
