<p>You would need supercapacitors, but you can make an inverter emulate inertia almost as well as flywheels, and more than well enough to not make a difference once you push the energy into a few kilometers of non-zero impedance grid.</p>

<p>Hum... The biggest hype on process engineering by the 00s was buffer size reduction. Because those buffers interfere with each other in chaotic ways, and they tend to turn "small problems that blow up soon, with small consequences" into "huge accumulated problem, that blows up hours after it appeared, with business-risking consequences".<p>Queues are pretty similar.</p>

<p>It feels like Greek mythology should have some metaphor for "apparently simple structure that is so complex it leads anybody that studies it into madness". But I can't think of any name to put there.<p>Maybe the idea of complexity is too modern.</p>

<p>The box is stochastic by design, and has an untraceable amount of complexity between its context and output by nature.<p>It may be fun to look at inputs and outputs, but it's not hackable and trying to map one into the other is more like astrology than a science.</p>

<p>Weird baseless push for AI on the end, with no reasoning, no goal, no claim of gain. "Just go and use AI, people, developers must adopt new things."<p>It's not the first article I've read recently that is an ad for AI after a short context pretending to criticize it, with nothing connecting them.</p>

<p>Well, the plugin developers can't really do anything about it.<p>And it's the one thing the LLM developers have been trying to fix for the last 2 years. Apparently, even at the cost of some other functionality. It's not like they can do it reliably.</p>

<p>> It serves the US Energy Dominance Agenda<p>I can believe the US/UK oil companies believe that.<p>It may even be true, because the energy transition caps the entire future opportunity for oil/gas sales, and all the producers have been trying to capture a larger share of that pie for the last 2 years or so.<p>But this intervention is so heavy-handed that it is visibly destroying that future market. It looks like all oil companies will lose a lot because of it, US/UK ones included.<p>> The Trump administration does not care about "its" population.<p>Yes, he's trying to govern like an oligarch. We will see in November if this was a good choice or if the US is still too democratic for this to work. Or earlier if he tries to avoid that test.</p>

<p>They mostly don't.<p>Or rather, when other countries say "sanctions", they are almost always talking about something completely different than the United States.</p>

<p>Hum... That's a huge conclusion from a single graph, I expected to see more data.<p>The jobs openings / unemployed close but a bit larger than 1 is the expected value when nothing is turning the economy completely upside down right now. It means there is no new shock that is too fast for people to adapt.<p>What is surprising, yes, because I could easily name half a dozen shocks that I would expect to see there. But it seems US people are adapting quickly right now, or things are canceling out.</p>

<p>If a company accumulates capital, it becomes vulnerable to the principal agent problem, and coops are way more vulnerable here than centralized companies.<p>If a company doesn't accumulate capital, it doesn't scale in complexity. It can grow by having more people do more of the same things, but it can't move into markets that demand anything complex.</p>

<p>Some people would use the GP's idea that way, yes.<p>But that's absolutely not what he's describing. He wants not to think about it, that's exactly the opposite of a disorder.<p>Anyway, an LLM assistant is also exactly the worst technology to use there, on every dimension.</p>

<p>Funny thing, the uber's investor results from last year only mentions "profit" once, in a motivating paragraph where they say they will be great.<p>But it's famous for having collapsed after their IPO. It took 4 years to get back at the same nominal valuation (not inflation corrected), and after all the 2020s inflation it is still at 2x the initial price.</p>
