Starlink, the satellite constellation from @elonmusk ‘s @SpaceX, will change the world.

It will attack mobile telecom monopolies around the world and they won’t be able to compete.

Summary thread of the article below [1/]

caseyhandmer.wordpress.com/2019/11/02/sta…
SpaceX has an developed an unfair advantage: by dramatically reducing the cost of space launches, they can afford to send satellites to space at a price nobody can compete with.

It’s so low that few other companies can replicate it easily, soon
[2/
So SpaceX will send hundreds of thousands of satellites to orbit, covering all earth with enough bandwidth and at a low enough cost that it will be much much cheaper than cable for billions of people, starting with rural and suburban areas.
[3/]
So they might have billions of customers in telecoms, one of the most lucrative industries in the world.

The more customers, the more money, the more satellites, the more launches, the cheaper the launching, the cheaper satel cost, the lower the price, the more customers...
[4/
All of that will in turn make SpaceX an even stronger company, and might finance the colonization of Mars.

@elonmusk wants 1M ppl in Mars. If they cost $100k each, that’s $100B.

If Starlink has 1B customers paying $5/month, it pays for Mars w/ a few years of profits
[5/5]

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: 🧵 Image
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? Image
1. History: This is where Europeans came from, and the place they settled first

Also, the St Lawrence river is naturally navigable until Montréal by seafaring ships—and up till the Great Lakes since the 1800s

That meant direct trade with Europe & the world➡️wealth Image

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! Image
You might also know that 70% of Canadians live in these 3 colored areas

These 3 areas are completely disconnected from each other Image

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 Image
3. North Korea is a dictatorship, but South Korea 🇰🇷 is no perfect democracy. All but ONE of🇰🇷's heads of state have had a troubled life... Image

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 Image
Image
2. North Koreans like making their buildings' form represent their function. This is the entrance of the Zoo in the capital, Pyongyang: Image
3. The tallest building in the country is empty!
The Ryugyong Hotel was never finished. This Blade-Runner-style building has been empty for decades. The gov put LEDs on one facade, to use it... for propagandaImage

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! Image
One of the main reasons is its industrial production: It's shrunk compared to similar countries Image

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 Image
Image
Image
Image
3. The main reason is because this region industrialized early. One of the reasons of that industrialization is because of the Bohemian Mountains and their coal and iron Image
