Nuclear is the best source of energy across nearly all the factors that matter. It's the safest, cleanest, densest, most sustainable, geopolitically stable, predictable, dispatchable, and can be cheap.

1. SAFEST
It kills 1000x less than coal Living close to a nuclear power plant for one year gives you less radiation than eating a banana (graph is logarithmic)

Over 80% of Canada's population lives in these 3 areas.
Why these 3?
Why so disconnected?
What are the consequences of that?
Here's why: 🧵 ST LAWRENCE VALLEY & GREAT LAKES
About 55% of Canadians live here, on the riverbanks of the St Lawrence River and the Great Lakes. Why?

And as soon as you go a bit farther north of the St Lawrence, population disappears. Why?

Trump claims Canada should become the 51st US state
How much truth is there to this claim?
These maps tell us: You probably know that 50% of Canadians live below this line

80% of Canadians live within 100 miles of the border with the US!

10 surprising things I've learned about Korea as I research it:

1. You might have seen the map of day & night lights in North vs South Korea, but have you compared it with population density? 2. Seoul is just monstrous. Its metro area covers 12% of South Korea🇰🇷's surface but 50% of its population

I think the craziness of North Korea is most apparent in its architecture. 7 examples:

1. The Science & Technology complex has the shape of an atom from above
2. North Koreans like making their buildings' form represent their function. This is the entrance of the Zoo in the capital, Pyongyang:

The stupidest German policy of the last decade: closing its nuclear power plants

These are Germany's sources of electricity vs what they could have been if they had kept nuclear open:

• This has destroyed Germany's industry
• The new gov can reverse this
🧵 Germany's economy is in tatters. It's one of the slowest-growing rich economies. It has been in recession in 2023 and 2024!

This Sunday are Germany's elections
These are the best maps to understand the country:
Why is it so rich?
What makes it special?
What lies in its future?

1. We can still tell the East/West divide, 35 years after the reunification. These are Germany's phantom borders 2. Before WW2, East Germany had more:
• Working class ppl
• Vote left
• Women working
• Births out of wedlock
• Protestantism

UNPRECEDENTED
The singularity is near. We're 1-6 years away from AGI according to:
1. Prediction markets
2. Insider insights
3. Benchmarks
4. Lack of barriers to growth
5. Current progress

This breakneck speed of AI progress is illustrated by OpenAI's o3 and DeepSeek🧵 1. Prediction Markets:
Average bet on AGI: November 2030
Mode: June 2027

This remote corner of the US has something unique that might soon make it one of the most important cities in the world—the city of the future. It is officially Boca Chica today, but it might soon become Starbase 🧵 This point at the south of Texas is the southernmost point in the continental US

We should transform Guantanamo Bay into a 21st Century Hong Kong 🧵 Hong Kong was a deep water port surrounded by a Communist country—China

By building up the port, urbanizing the surrounding area, making business easy, and taxing little, Hong Kong showed China what capitalism could do by becoming a global port and financial center

The answer to this is FASCINATING, it goes beyond what most people think, and its ramifications help explain ALL of the US's climate and population

Here's what people already know: rain
Water basically stops halfway through the US
But why?

https://twitter.com/rememberlenny/status/1875031224659644856

The next thing people will say is: mountains. The US West has tons of them! See map

Mountains stop rain, and the US West is mountainous, so that's why rain doesn't make it farther, right?
Wrong!

Why are the top 20 US cities where they are? (including metropolitan areas): 🧵

1. New York: It became the trading hub between the Great Lakes and the Atlantic regions when it built its canals through the Appalachians

https://x.com/tomaspueyo/status/1645489760222289937

2. Los Angeles:
• Trading hub between the world (Pacific) and the US (railways)
• Weather + biggest coastal valley on the Pacific➡️agriculture & cheap building
• Oil
• Landscapes + far from the East Coast centers of power➡️Attracted the film industry

People think we must shrink the world's population to be happy, but they're wrong

A world with shrinking population would be decaying, poor, brutal, violent, hopeless

A world with 100 billion people would be dynamic, rich, innovative, peaceful, hopeful
🧵 1. In the last 2 centuries, the world got better as the population exploded:
• Richer
• Live older
• Lower child mortality

We can raise our population on Earth from 8 billion to 100B humans if we want to

Would we starve?
Be too crowded?
Would pollution explode?
Ecosystems collapse?

No! Don't believe alarmist degrowthers. This is why they're wrong: 🧵 Degrowthers put a label to "how many humans can the Earth sustain": carrying capacity

Their estimates vary wildly
Wait, what? What a surprise, the mode of their estimates is 8B—exactly the current number of ppl on Earth

WHAT A COINCIDENCE!

Can desalinated water deliver a future of infinite water?
Yes!
• It's cheap
• It will get even cheaper
• Limited pollution
• Some countries already live off of it

We can transform deserts into paradise. And some countries are already on that path:🧵 Crazy fact:
Over half of Israel's freshwater is desalinated from the Mediterranean!
And the vast majority of its tap water is desalinated too!
And it costs less than municipal water in a city like LA!

President-elect @realDonaldTrump could own the environmentalists by solving global warming on his first day in office, and do it for 0.1% of current climate investments

Here's how: sulfate injection 🧵 1. GLOBAL WARMING
2024 is the 1st year we pass 1.5ºC above pre-industrial levels
This is caused by CO2
Some side-effects of this CO2 are good, but it's undeniable that the planet is warming fast, and it could create some nasty pbms

Should you be able to experiment on your own cancer?

This expert virologist did. It was the 3rd time her cancer appeared. It didn't bode well. So she injected viruses in her tumor and it shrunk.

But most journals didn't want to publish her results. Why? Because they're dumb 🧵

https://twitter.com/Nature/status/1855079763129299141

Beata Halassy got cancer in 2016, then again in 2018, and again in 2020. That looked awfully bad. She knew if she continued in the traditional route, her cancer might eventually prevail. So she decided to try what she knew about: viruses

Now that Starship can land, it's ready to go to Mars in 2026

Why then?
How will it go?
Why don't we need a Moon station for pit stops?
When will humans go?
🧵 1. Why 2026?
As the Sun travels through space, its planets follow it

Starship is going to change humanity well beyond going to Mars: It will transform the Earth too because the cost of sending stuff to space is about to drop by 10x

A tip of this future comes from the Silk Road [1/6] Why was it called Silk Road? Because silk is expensive & light

Transportation costs depend on distance and weight: The longer the distance and the heavier the goods, the more expensive transportation

So over long distances, only light & valuable goods could be sold—like silk

Lebanon could be rich, but it's chaotic. Why?
Geography, which is reflected on its flag
You can understand it with just these maps:
🧵 Here's the population density in the Middle East

Lebanon is in the small region of the Levant, surrounded by 4 traditional superpowers:
1. Asia Minor—now Turkey
2. Mesopotamia—now mostly Iraq
3. Persia—now Iran
4. Egypt
5. And also has sea access for Mediterranean superpowers

Every American is poorer because of longshoremen's position

The worst is not the $1½-5 Billion per day the strike would cost the US economy

The worst is not their outsized salaries It's not even the known ties they have with organized crime, or their extraction of rents for work they never did
