Je vais dire quelque chose qui va sûrement en choquer plusieurs, mais la couverture médiatique OMNIPRÉSENTE des élections de mi-mandat démontre que le Québec et le Canada ne seront probablement jamais le 51e État américain, mais qu’ils le sont de facto, mentalement.
On parle dix fois plus d'une élection qui ne met même pas en jeu le poste de président que de nos propres élections ou encore d'une élection historique en Colombie-Britannique dont tout le monde se contresaintciboirisait
La première fois où ça m'avait sauté aux yeux, c'était lors du débat de la vice-présidence en 2024, où des journalistes québécois commentaient ça en direct sur X.
En parallèle, on se fait croire qu'on est européens alors que 95 % des gens sont probablement incapables de nommer le chancelier allemand ou encore le ministre de l'Intérieur français, mais connaissent Trump, Vance, Rubio, Mamdani, Bush, Obama, AOC, Harris, Biden, etc. etc.
Bref, c'est peut-être ce qui est venu le plus heurter les gens dans toutes ces fanfaronnades de Trump sur le 51e État : le rappel que, malgré tout leur antiaméricanisme, les Canadiens (et les Québécois) sont, à quelque part au fond d'eux, des Américains de banlieue.

Walmart's CEO received $29.24 million in annual compensation. Walmart employs over 2 million people.
Take his entire compensation and distribute it equally among employees, and each gets less than $15 a year, or roughly 0.7 cents an hour.
Now raise everyone's wages by $5 an hour and you're looking at over $20 billion annually.
This is why understanding basic arithmetic matters more than being outraged by big numbers.

My kid asked what it was like living in the same era as those visionaries and geniuses. We quickly realized those eras were often riddled with turmoil.
Da Vinci lived amid uncertainty—the printing press’s spread, the Italian Wars, and religious upheaval that broke from the Pope.
Newton was born during civil wars between Parliament and the monarchy; the Great Plague later forced him into isolation at Woolsthorpe.
Einstein and many colleagues endured WWII’s conflicts.
Historical trajectories often rhymed with rise and fall. We thought rapid progress came from tranquility, but it rose from the most combustible moments, like the Big Bang. It’s a feature, not a bug. Then the dust settled, temperatures fell, and we calmly enjoyed the fruit they bore.

OK let’s imagine that! $500M would fund Medicare for exactly 4 hours. Hospital closed by lunch.
Medicare costs us $1.2T a year. Thats $2.7B per day. You people literally have no clue how anything works. You elect people who are financially illiterate, and everything gets worse.

“ Nigerian MAGAs” is a slur for anyone who doesn’t agree with leftist ideology. It’s how Tinubu’s people refer to their opposition as “the mob.” One of the known strategies for asserting dominance is grouping opponents into one rigid group. It can also serve as a basis for justifying cruelty towards that group.
Sub-Saharan Africans don’t share the same imperatives as Black Americans. It doesn’t mean one is more important than the other. But they don’t have to.
A common argument against the preceding point is that, when you’re abroad, they’d group all of you together as Black. What makes this argument extremely stupid is that you can’t speak against “white supremacy” narratives yet use such narratives as a basis for your proposed Black solidarity.
If you think Dark skin people aren’t a monolith then you either acknowledge it, or go fuck yourself.
Trump has been such a boon to the Liberal Party of Canada. Why blame the party that's been in charge of the country for over a decade for your troubles when the leaders can just point fingers to the orange man down south.

What was the poverty rate, HDI, Literacy rate, access to public services etc of that time period?
If you keep thinking like this you'll never understand what problems need to be solved and why they exist
Nigeria has never been an industrialized country and never been wealthy
"Labor shortage" is business code for wage suppression.
Prime Minister Mark Carney is facing growing pressure from business groups to allow more immigration to address Canada’s labor needs, but the prospect of welcoming more migrants carries political risk for him bloomberg.com/news/articles/…

To understand most things Musk says, you have to understand that engineers are born, not made. You have to understand that he has always been an engineer and pretty much nothing else. And you have to understand that 99% of an engineer's job isn't to create a thing... it's to teach ourselves how to create a thing.
So when he says cooling in space is "easy", that doesn't mean what normies mean by "easy", which is "doesn't take a lot of resources, time, or expense".
He means what engineers mean by "easy", which is "contains no unsolved problems".
You take in X amount of energy, you know it's all gonna end up as heat, you know that to radiate X amount of heat you need Y amount of radiator. It's all just math.
If you build a satellite that takes in 2X energy, you need 2Y radiator.
There's no unsolved problem, here. There's nothing to figure out. You know the answer. You just have to design the layout.
If you're been beating your head against "how land booster" and "how make engine not boom" and "how make rocket lighter" for years, this is like drawing stick figures by comparison.
So if guy comes along and says "vacuum is a near-perfect insulator", which is both technically true and completely irrelevant, of course Musk is gonna call guy a retard.
Because guy has just revealed that he doesn't understand the basic nature of the problem, or of the design conversation.
The only significance that "vacuum is a near-perfect insulator" has is that it means you can't do cooling in space the same way you would on Earth.
Well, duh.
We've known that since we first understood what space is.
And we've successfully dealt with that challenge since the very first times we put things in space.
Fusion containment is hard. Rocket engines are hard. New AI capabilities are hard. Cheap and reliable manufacturing at scale is hard. Estimating costs and schedules is hard.
Waste heat is not hard.
Yeah, much easier to cool in space.
~1300 W/m^2 is easily achievable for an aluminum radiator pointed away from the Sun, as it is mostly just seeing cosmic background radiation at ~3 degrees above absolute zero!
Solar panels generate ~250 W/m^2, so you should expect them to have ~5 times the area of the radiator. Most of the mass of the satellite is solar panels.

Many have argued that western countries are rich today off the money they made from colonization and the slave trade,
Hard for me to buy that because we have an entire continent of countries that just made a killing from resource sales in the 2000s and the money is already gone.

This tweet has gotten 2 million views and is wrong.
Musk doesn't think space cooling is easier because space is cold. He thinks its easier because it's a strait forward engineering problem that scales well.
Cooling in space is indeed difficult, because vacuum is an insulator.
But it's also straightforward, you just need a radiator.
Since 99% of the heat you are radiating comes from power consumption produced by solar panels, the amount of radiator panels equals a percentage of solar panels. It's around 25%.
The International Space Station has ~2,500 m² of photovoltaic panels generating power, and ~645 m² dissipating the heat.
There is no scale problem like there is on earth -- you can just keep building bigger and bigger and bigger.
Scaling is what makes cooling harder on earth. The bigger the data center, the more difficult the cooling. This comes not just from the engineering challenges but also the political challenges from communities rejecting huge data centers, taxes, etc.
However, we haven't built anything larger than the ISS for radiators. We have a lot still to discover, such as micrometeorites puncturing fluid lines. I wouldn't bet on space data center, but Musk isn't making simple errors by thinking that space is "cold" instead of "insulated".
My respect for Elon Musk has mostly vanished, but I still thought that at least he is a good engineer (Teslas are great cars). But that last bit also got a blow after hearing him say that it is easier to "cool things down" in space. The opposite is true. A vacuum is the best possible isolator. In space you can only dissipate heat through radiation. It is extremely unlikely these data centers in space will ever happen (and certainly not in our lifetimes).

The total difficulty of cooling in space is vastly harder than on the ground
But 99.9999% of that challenge is Starship
Once you have the ability to get huge amounts of mass into space cheaply, it is genuinely easier to cool things in space
Your cooling system is passive
Just a giant piece of metal that is a) light w/ b) high thermal conductivity
Aluminum is a good candidate
And then you have a working fluid that just circulates forever inside the metal structure
Ammonia is historical industry standard for radiators in space
You need a fluid where the critical point is optimized around the temperature of the chips
The working fluid goes from liquid phase to gas phase near the chips, and this change in density drives the hotter gas to pump heat through a loop
The high thermal conductivity of aluminum rips heat out of the fluid and black body radiation ejects heat into space
Black body radiation goes like temperature to the 4th power so the hotter you can run chips and hotter you can get the working fluid the better you can shed heat
It's honestly a way simpler system than on the ground
