science4sail··on Companies Lobby Against Giving the Military the Right to Repair
I think that's a common scenario in historical fiction depicting conflicts between upright barbarians and decadent empires. The empire could easily crush the barbarians, but it's too preoccupied with internal politics and power struggles to do so.
science4sail··on Human brain organoid bioprocessors now available to rent for $500 per month
I can see how this would be useful for research, but on the other hand it feels like a step towards the dystopian servitors[0] from Warhammer 40k.

science4sail··on The Social Recession Is Accelerating
I think that historical cycles have been a popular topic ever since at least the days of Socrates and his philosophical peers.

That said, have any of these predictions ever managed to stop the cycle? As far as I know, both Turchin and Ibn Khaldun (who Turchin calls out a lot in his books) felt that such cycles were inevitable. The more common response to these predictions seems to be some variant of "this is cherry-picked data, our society is different!"

Or are such predictions instead intended to speed the advent of the next cycle? Perhaps we should be like King Wen Zhou in pre-imperial China, watching the skies for a sign from heaven to bring about the new age.

science4sail··on San Francisco officials weigh in on departure of X headquarters: 'Good riddance'
There are only two ways for a city to relieve a housing shortage: either build more housing or make the city less desirable to live in. SF has decided that the first is impossible, so they're going with the second.
science4sail··on Genghis Khan, trade warrior (2021)
To be fair, the Mongol empire did end up disintegrating in a few generations. Kublai Khan was the de jure ruler of a united empire, but in practice the western periphery of the empire was drifting away.

> If you want to keep the empire unified, you need a civilian government and civilian institutions to keep the military under control.

But then you run into another classic political science problem: how do civilian institutions keep the military under control? Why can't the military simply shoot the civilians and institute a junta?

science4sail··on UN Cybercrime Convention to Overrule Bank Secrecy
That's the dismal tradeoff with such things. Anything that can be used to help dissidents can also be used to help organized crime. Cryptocurrency, end-to-end encryption, Tor all ended up with this fate.

That's because from the perspective of an authoritarian state, there is no meaningful difference between political activists and ransomware gangs. Both are dastardly cybercriminals.

science4sail··on It is now easier to pass AP tests
I think that grade inflation is a tough topic.

On one hand, you could argue that grade inflation is actually a good thing: if pedagogical methods are getting better over time, then you should naturally expect grades to rise if standards stay the same. After all, we no longer expect literacy to be limited to the rich and/or highly educated.

On the other hand, grade inflation makes it harder to filter above-average students from below-average students. You could combat this by grading on a curve or by making exams harder, but this risks driving students into deleterious zero-sum behaviors - see Asian "cram schools" or American "tiger parenting".

On the gripping hand, maybe grades are the wrong thing to focus on. There does exist the argument that all social classes need smart people, not just the upper-middle/upper classes. Perhaps we should be focusing on improving living standards across society rather than attempting to brain-drain the working class. But this sounds like exactly the sort of thing that would be used to justify aristocracy.

science4sail··on CrowdStrike CEO summoned to explain epic fail to US Homeland Security committee
So 2025 will be the year of GNU Hurd on desktop?
science4sail··on Money and Happiness: Extended Evidence Against Satiation
> The results suggest that the positive association between money and happiness continues far up the economic ladder, and that the magnitude of the differences can be substantial.

Sometimes I wonder if the folk wisdom that "money doesn't buy happiness" is an attempt by the poor to make themselves feel better about their own life situations.

science4sail··on Scientists create a cell that precludes malignant growth
I think that the original Jurassic Park book mentioned that the dinosaurs found a way to get around the lysine issue.

After all, humans can't produce lysine either, and we propagate in the wild just fine!

science4sail··on New parents in Baltimore could get a $1k 'baby bonus' to fight child poverty
From a pure economic incentives perspective, I don't think that wealthy countries will solve their birth rate issues until parents are financially on par with or even ahead of childfree people.

It's hard to see how this could be done without heavy transfer payments/subsidies or restricting careers/promotions based on family size. These will of course generate all sorts of adverse side effects.

As a result, the general solution is to use immigration to blunt labor shortages and hope that natural selection will eventually favor natalist psychologies/cultures. This too has a lot of negative side effects.

science4sail··on Modern-day spying: sometimes old technology is more secure
Can you please provide evidence that this isn't a scam website? It's pretty common for scammers to prey on scam victims since they're often desperate and emotionally compromised.
science4sail··on Supreme Court rules ex-presidents have immunity for official acts
What if he/she assassinates the impeachers as an "official act"? That might be an example of Gödel's Loophole.

science4sail··on Gen Z Plumbers and Construction Workers Are Making BlueCollar Cool
I think that USA culture at least has certainly gone too far in the direction of "college degree = white collar job = comfortable middle-class lifestyle". From what I understand, the PRC ironically also ended up in a similar situation with a vast oversupply of college graduates.

That said, the article focuses on people who have two jobs (their day job and also social media influencing), so I wonder if this sort of stuff is an overcorrection: romanticization of blue-collar jobs with little discussion of its health risks and working conditions.

science4sail··on Most life on Earth is dormant, after pulling an 'emergency brake'
I recall reading a Jack Vance novel where cannibals used cryogenic sleepers as a convenient supply of preserved food.
science4sail··on Most life on Earth is dormant, after pulling an 'emergency brake'
That's probably a motivating factor for defrosting your first few hundred/thousand mummies, but would the "interest" factor still be there for the millionth mummy?
science4sail··on ASML and TSMC Can Disable Chip Machines If China Invades Taiwan
The CCP sees the Taiwanese as rebel separatists, so renaming "Republic of China" to "Republic of Taiwan" would increase, not decrease, the odds of invasion by confirming their propaganda. The CCP wants the island of Taiwan itself; it doesn't care about the ROC's claims on the mainland.
science4sail··on Who Wants 30k Used Teslas?
You can live in a car, but you can't drive a house :)
science4sail··on The Star Destroyer and Imperial Military Doctrine
> they were willing to give a fighter to a random farm boy who happened to show up for a battle.

My impression was that Luke's X-Wing was his reward for saving Leia - in the same scene we see Han leave the Rebels while carrying a sizeable amount of money.

science4sail··on [dead]
I think that OP's post is likely to get flagged given the political content.

That said: I was shocked to walk by an anti-NATO "hands off Ukraine" protest shortly after the 2022 invasion. I delved into it a bit and there seemed to me to be at least two kinds of people who would have such a point of view.

* People with an extremely deontological morality: if they saw a runaway trolley, then they would never pull the lever. Some of these folks seem to have their beliefs so tied up in anti-Americanism, pacificism, and/or isolationism that they refuse to accept exceptional situations.

* Fanatical socialists who think that global unity among socialists is more important than national interests or human life - they usually point out how the First World War caused the demise of the Second International[0]. This reminds me of a reprehensible argument apocryphally attributed to Lenin: socialists shouldn't try to make peoples' quality-of-life better under capitalism (indeed they should try to make life worse) because doing so would slow the coming of the Revolution.

science4sail··on NASA's Voyager 1 Resumes Sending Engineering Updates to Earth
> compute more than several galaxies full of classical humans

Unfortunately the simulated classical humans in your Matrioshka Brain will want to mine Bitcoin, which means that our digital descendants will have to become a true interstellar species anyway in order to convert the Laniakea Supercluster into coin-mining computronium.

science4sail··on Tesla risks losing its lead without an inexpensive EV
> Tesla is working on a $25k auto right now that should be available in 2026.

I thought that the Model 2 had been canceled?

Did they run out of funding/money? The press release doesn't give a clear reason.
science4sail··on Roll-to-roll fabricated perovskite solar cells under ambient room conditions
* That Wikipedia link gives an average global energy consumption of 4.810^12 watts (assuming 11.63 TWh per MToE). The solar insolation of Earth is about 210^17 watts The total power output of the Sun is about 410^26 watts. The total solar power output of the Milky Way galaxy is about 410^37 watts

Assuming exponential growth and assuming 20% utilization, that gives us

A fully solar economy in ~13 years * Kardashev Type 1 in ~59 years * Kardashev Type 2 in ~272 years * Kardashev Type 3 in ~381 years

science4sail··on Moderna mRNA-4157 (V90) news for head and neck cancer patients like me
Isn't it a problem of incentives? No one gets penalized if a lifesaving drug gets delayed, but heads will roll if an experimental drug turns out to have horrible side effects and/or financial costs - especially if the test subjects disproportionately belong to a politically-sensitive demographic.

Pandemics are an edge case: it's socially acceptable to violate political and ethical norms during an emergency.

science4sail··on How deep does life go?
Why not just move the Earth? You could do that over a few million years using a gravity tractor.

science4sail··on Pentaborane(9)
> The propellant mix that would produce the greatest specific impulse for a rocket motor is sometimes given as oxygen difluoride and pentaborane.

Spicy! How does that compare to metallic hydrogen and metastable helium?

science4sail··on The true cost of Japan's bullet train: costs and environmental degradation
Most of the objections in the article (costs, environmental impact of tunneling, eminent domain) could be applied to any major infrastructure project. I'm particularly irked by the concerns about energy use - at 500 km/h, Linear would primarily compete with air travel, so that's where the comparison should be made.

On one hand, if you stop to appease every stakeholder, then you will end up in an eternal quagmire like the California HSR project. On the other hand though, if you make a practice of expedited construction, then you could end up copying the PRC and stomping on anyone that dares to dissent against national prestige projects.

science4sail··on Some colleges will soon charge $100k a year – how did this happen?
> Let's face it, everything has become more expensive. The Five Guys meal of a little cheeseburger, little fries, and regular drink which cost me $12 4 years ago in March, 2020 (I keep records), would cost me $17-18 today (I checked the prices today at noon and walked away). That's a 40-50% increase.

Couldn't this just be combated using shrinkflation? I'm sure that rice, beans, ramen, and other grad student fare is still cheap yet provides enough nutrients to study.

After all, these are supposed to be institutions of the mind, not institutions of the stomach.

science4sail··on March job growth zoomed: payrolls jumped by 303,000, unemployment drops to 3.8%
I imagine that an interesting sociological topic could be fashion trends and mass hysteria among business elites.
