> Grid scale lithium batteries have an effective lifecycle of 15 years. In this potential future, global lithium reserves would actually start getting choked up before the 2050 goal.

I think the long-term solutions here are not grid-scale lithium batteries, but pumped hydro, flow batteries, or compressed air. Lithium batteries have just gotten a bit ahead on the technological growth curve because of the recent boom in production from phones and EVs, but liquid flow batteries can be made using common elements, and are likely to be cost-effective once the tech gets worked out better.

So: I don't think we can say "lithium energy storage is unfeasible large-scale and long-term" and thus conclude that nuclear is inevitable, unless we also look at all the other storage alternatives.


The main reason lithium batteries are used in cars and electronics is because they offer some of the best energy storage per kilogram. That's really important for something meant to be portable, but it's completely irrelevant for a large permanent installation.

> The article is typical handwavy crap which is popular among people living in what amounts to subtropics

To be fair, 90% of the population lives within 45 degrees of the equator. If we're talking about global energy solutions for CO2 reduction, we can go a long way just by focusing on what works in these areas of the globe.

The article does also point out that hydro/wind are going to be important at higher latitudes in winter, but they also acknowledge that they don't account for seasonal variation in demand. That's the biggest flaw I can find in the analysis.

FWIW: I'm down in a mild arid climate at 35N, and yeah, 90% of our winter days are nearly sunny, even when the lows are in the teens. It's a different world for sure.


Most space heating is in the Northern parts though, so those are the ones that need to be addressed. There are solutions that are a pareto improvement, but it's a coordination problem and the USA is sufficiently broken and unable to solve those.

> so those are the ones that need to be addressed.

Make energy so expensive that people have to move away or burn their old house.


You'd think, but then you get Northeastern states paying poor people thousands of dollars a year to keep their oil heat going.

Supposedly the issue was less bomb accuracy and more bad intel

Weird that we can afford how many hundreds of thousands per bomb but can't be bothered to pay entry level wages to manually verify each site. I'm sure the DoD has access to something even better than Google Maps.

Does it matter, at this point? If you go and tell someone who’s lost their home and half their family in a strike, "oops, it was just bad intel", do they hate you less?

Oh no, if anything I think bad intel is probably worse

The issue was starting an unnecessary war. When you did, then all the deaths are on you.

Yeah, but… I think if you’re bombing a child’s school because of bad intel, the deaths are on you either way. We’re not going to be like “oh, this war was necessary, which means it’s no biggie that you accidentally killed two hundred children because you didn’t do your DD”

Ostensibly, it wasn't unnecessary to those who started it.

its always that, and absolutely nobody cares

I sometimes wonder if our modern philosophy of requiring intentionality for crimes is the wrong way. You can launder intentionality be not trying too hard. If you try really weakly, it's called negligence but even that isn't as morally bad as intentionality. Perhaps we should forget about trying to read the mind of a state or criminal and only judge them by their actions.

In my country, punishments for killing people with deliberate violence varies from 8 months home detention (bus driver punched a passenger in the face, knocking him out so he fell backward and cracked his head on the ground), to several decades (man grabbed scissors from the kitchen, ran to his ex girlfriend's room, and stabbed her repeatedly). Both victims are equally dead but the courts decided that the perpetrators' feelings mattered far more than what they did. Perhaps if the bus driver had been weaker and needed a weapon, he'd be in prison for 10 years instead of free? Perhaps if the ex-boyfriend had used his fists outdoors on a concrete pavement, he'd be free? Seems grossly unfair.


For the most part, these mushrooms eat dead trees, so

I made a face, reading this article. They present the US gov't's very large and scary liabilities and future obligations, but they don't present the other side of the picture, the future income streams. (How much can the US government realistically expect to earn annually via taxation?)

Without being able to compare future liabilities to future income, we're lacking critical context. It's like they wrote half an article; kinda frustrating.


There is no feasible scenario where tax revenues will allow the US government to pay a 39 Trillion, soon to be 40 Trillion debt. And paying the debt its not even in discussion right now.

What is in discussion, are the multiple, very feasible, and very realistic scenarios, where an increase in interest rates, and a run from the dollar...Will force the US government to spend over 80% of the tax revenue, JUST TO SERVICE the debt interest....


I know a way.

Close out enough debt to make what's left serviceable. Thank our richest for their sacrifice for the nation's greater good.

The alternative is that they take the money and run. Or start WWIII. There is no in-between.


> Most likely outcome is that they make huge paper profits that are then absolutely worthless because the dollar collapses

Seems like it'd be pretty easy to diversify into inflation-protected assets after taking big profits.

But I also don't see the dollar collapsing any time soon. The dollar's strength is built on the US economy, and the US economy is still one of the strongest in the world, with high productivity per person. We'll see some inflation, sure, but nothing that the rich insider traders can't hedge against.

I do not expect that there will be any real justice here. They're not gutting the average American -- they're bleeding us, extracting a small enough amount of value that they can get away with it. And we don't live in a just world.


There is no "inflation-protected" asset if the economy collapses. You can't hedge societal unrest. The aliens don't want bitcoins.

One of the reasons behind the dollar strength is that the US has a huge population.

Even if the central bank might does a bad job and make a mess of the economy, the activity of 350 million people is hard to ignore.

Is it enough to _fully_ sustain the US dollar?

Who knows, but at least there is a floor, even if everybody stopped using US dollars for international trade.


U.S. has only 4% of the global population.

I think this is a big part of both the impact of globalization and the U.S's waning power. Back around 1950, right after WW2, the "first world" (the developed west, not including Russia or Warsaw Pact countries) had a total population of just over 500M, and the U.S. was 150M of those, just under 1/3. And the remainder were largely dependent upon U.S. capital, machinery, and technology, having just bombed each other back to pre-industrial times.

Today, the developed world is about 3-4B people, and the U.S. is 350M of them, less than 10%. China alone has lifted about 500M people out of poverty and into the middle class in the last 2 decades, a population larger than the total population of the middle class in the U.S. The population of Asia is around 4.86B, 15x the size of the United States, and an increasingly large number of them are living a lifestyle close to what Americans enjoy.


I mean sure but... How much do you want to hold the Yuan? China has always had a huge population but nobody considered the Yuan the same way.

Nobody thinks of the Indian rupee this way today.


>Seems like it'd be pretty easy to diversify into inflation-protected assets after taking big profits.

Assets are yours only as long as there's a government to enforce your ownership rights over those assets for you. In case of government or societal collapse, your physical assets then are free for the taking to the ones with the most men with the most guns, and your paper assets are worthless.


I believe the dollars strength is built on its unassailability as the petrodollar and foreign reserve currency, which lets the fed set interest rates and print money while creating less inflation than any other currency. The world looks very very different when energy markets aren’t fulfilled in dollars in ways that most citizens won’t understand.

That’s false. The petrodollar is irrelevant because two non-US companies trading using an intermediate currency like the USD create a balanced buy and sell of the intermediary.

If the petrodollar is irrelevant, why is Iran insisting that anything transiting the straight of Hormuz be bought using the Chinese Yen?

Because China has a controlled currency and can lock flows back out.

Please do enough research to at least get the right currency before engaging in these discussions.

The forex markets are so extremely liquid and deep that trading in USD is no different than trading in any other free floating high volume currency.

Petrodollar might have mattered in 1975 when you couldn’t swap 100 million USD for 100 million euros in 2 seconds without even moving the market.


Yuan. Not Yen. Iran shouldn’t be insisting anything.

But why is Iran insisting the Chinese Yuan be used? Because they're idiots?

Because Petrodollars make our global economy work, and Iran wants their partner China to be in control! If Americans lose sight of their need to maintain their role as *THE* lingua franca of international trade, then all hell is lost. The US cannot afford its military without massive consequences if it can't raise extraordinarily cheap debt through purchases of oil in US dollars immediately turned around to buy US debt to maintain that money's value.


Investment companies own only about 2% of the housing market, and most of these are rented out. Investment companies aren't really the cause of housing prices remaining high - in moderate- and high-demand areas, we simply aren't building enough to keep up with demand.


It's quite possible that the rich will essentially form a new economy.

They build the robots to build the factories, run the mines, build the solar farms, run the research labs, repair the robots, etc. They sell to and buy from each other.


Early steam engines did not produce large amounts of power on demand, though. They produced small amounts of power, were a hassle to fuel and maintain, and broke often. It was reasonable that the engineers of the 1700s said "well, until someone improves on this, it's not worth using"..

.. which is not far off from what people said about ChatGPT in 2022.

I don't know how long it'll take for AI to be as broadly impactful as the steam engine was, but.. it's definitely coming. I expect the world to look radically different in 50 years.


> Same with PhDs - is there a shortage of them? Does adding potentially infinite PhDs (whatever they are) to a project make it better, or does it just make... more?

Yes, there is still a large demand for people with analytical thinking, a deep knowledge base, and good problem-solving skills. This demand shows up broadly across STEM fields, and it's a major reason that these fields pay relatively high.

Even just thinking of R&D, there is an immense amount of work left to be done in basic science. Research is throttled partly by a lack of cheap graduate lab labor. (If that physical + mental labor became much cheaper, the costs of research would shift - what does it take to get reagants? What does it take to build more lab space, and provide water and light? Etc.)

The present issue is that current AI does not really offer the same capabilities as a good grad student or PhD. Not just physically, as in, we don't have good robotics yet, but mentally. LLMs do not exhibit good judgment or problem-solving skills, like a good PhD does. And they don't exhibit continual learning.

No clue on when these will change, but yes, a cheap AI with solid problem-solving skills and good judgment would absolutely upend our economy.
