<p>We are at a fork in the road with lots of potential darkness, but simply thinking any old social safety net is going to work is not going to cut it. Nets can be, and generally are, used to capture.<p>An interesting multi-pronged approach is post labor economics which is being promoted by David Shapiro:  <a href="https://www.youtube.com/@DaveShap" rel="nofollow">https://www.youtube.com/@DaveShap</a><p>The basic premise is that currently we have households being supported by labor, capital, and transfers. With labor largely going away, the leaves capital and transfers. Relying on transfers alone will lead to ownership of the people by government. So we have to find ways to generate way more distributed capital ownership by the masses. This is what he plans, discusses, and promotes.</p>

<p>I'd be curious about their analysis of the Nvidia self-driving car project which uses world models(?) to train them in far more extensive scenarios, though simulated, than possible in real world case. That keynote was after this article of course.<p>But I did check their dismissive claim about the 90% coding at anthropic by watching the link they provided. The Anthropic guy said that 90% was achieved at various teams within Anthropic and also hedged about the exact nature of it; it is a messy metric to be precise about. I thought the other was not generous in interpreting it which makes me skeptical of the edge of the rest of the article.</p>

<p>The optimal version of a PE is to take a failing business and either turn it around or carve up assets and reallocate people to do something useful and profitable. The more a business is failing, the cheaper it is to takeover and for the PE to do the work of a fungus. But this process can also become a disease if it is too easy for them to takeover, taking a healthy host and carving it up. This is mimicked in real life when conditions turn a fungus into a hostile organism on something that is living; maybe it is just a little sick but the environmental conditions help the fungus more than it ought to leading to it being a killer instead of a resource freer.<p>The real question to ask is why can they take on so much debt? And for that, one needs to acknowledge the fact that, particularly for the well-connected, debt is easy to obtain as banks essentially create money for loans. There are constraints (otherwise the banks would make themselves trillionaires), but the constraint is not the quantity of money. This creation of money through lending leads to inflation which further supports operating via debt as those who take out loans see the real value of the loans decrease. The banks just made up the money so there isn't a direct loser from the inflation other than everyone who has to deal with increased prices. You can think of it as a broad, regressive tax on the population to fund these firms doing far more than they should.<p>With an actual constrained money supply tied to real wealth in the economy, the PE firms would have to focus on the best deals which means the businesses that are truly dying and their role is to turn the nonproductive assets into something productive.<p>---<p>I asked ChatGPT to critique my answer (which is unaltered above) and it said to tone down the lending being propped up by inflation and instead emphasized the following:<p>>Inflation can help leveraged borrowers, but in PE the bigger structural advantages are:
 • Interest deductibility (a massive tax subsidy to debt)
 • Limited liability (upside captured, downside partially socialized)
 • Fee extraction independent of performance
 • Ability to load debt onto the acquired company, not the PE fund<p>I then asked it to answer the question without regards to my context and it basically said PE is different because of<p>> • short ownership horizons
 • high leverage
 • strong control
 • financial returns as the primary goal<p>Here is the link to the short conversation if interested: <a href="https://chatgpt.com/share/6963a0de-7a04-8012-8c36-afef5dd74fb9" rel="nofollow">https://chatgpt.com/share/6963a0de-7a04-8012-8c36-afef5dd74f...</a></p>

<p>Why shouldn't her medical providers be responsible for continuing critical health care regardless of payment? Why is it on the employer who is only tangentially related to this versus the people actually charging large sums of money for medically necessary treatment?<p>Also, the same health insurance can be continued after termination (with some external payment, of course) in addition to medicaid probably being available. None of that may be easy for someone with mental issues to navigate, but that is systematic.<p>As for the minor extension, is it clear how long she was on leave and what the conversation had been before the termination? The post said that they asked for small time extension, but did not give any indication as to what was happening before, neither length of time employed before taking the leave, what caused the leave, what was said in terms of a return, how long the absence was, etc.  I feel like plugging in different answers for those questions would change how I feel about the culpability of the company in the current legal regime.</p>

<p>It is even a bit more scrambled such as this part: hcihw selcihev selcihev ot ot ot ot erauqs strap. Looking at the original site, that text is in various nested structures with the paragraphs having that kind of text. They have multiple bits of it being an article block with a .is-paywalled governing various behaviors such as showing ads. The scrambled text is in paragraphs within the separate article portions. Presumably they have a script that will decode it for those to login though I do not understand why they even provide the text? Why not just return it after login? Maybe it is total trash text and just there to pad it out like a lorum ipso. Kind of interesting.</p>

<p>EPR's point is that there is nothing mysterious from a classical perspective of being able to deduce this. They were arguing against the presentation of QM as to there being no fact of the matter about what the momentum is before the measurement and that it randomly becomes whatever it becomes when measured. Their point is that if both particles are randomly collapsing into their choices, then they should disagree at some point unless there is some nonlocal causation happening. Einstein rejected nonlocal causation, reasonable given what he knew at the time, and thus the momentum measurement result must already be preordained by something and it is then like the classical setup.<p>Bell's work was to show that it had to be the nonlocal causation.<p>>Do you know some more formal article discussing the proposed experiments?<p>I do not know of an article, but Maudlin's book Quantum Non-locality and Relativity goes through the various notions of locality and what QM says about it. There is a chapter about signaling and another about causation. It also covers the GHZ scheme which is a non-probablistic version demonstrating non-locality. It is pretty clean.<p>>Do you know some more formal article discussing the proposed experiments?<p>I have not read them, but my understanding that Siddhant Das is pursuing these and here is a link to his Arxiv papers which talk about arrival time experiments though I do not know if it is directly about these.<p><a href="https://arxiv.org/search/advanced?advanced=&terms-0-operator=AND&terms-0-term=Siddhant+das&terms-0-field=all&classification-physics=y&classification-physics_archives=all&classification-include_cross_list=include&date-filter_by=all_dates&date-year=&date-from_date=&date-to_date=&date-date_type=submitted_date&abstracts=show&size=50&order=-announced_date_first" rel="nofollow">https://arxiv.org/search/advanced?advanced=&terms-0-operator...</a></p>

<p>In EPR, it is critical that it is the same measurement. Bell explores doing different measurements. For EPR, they assumed that if you can predict with certainty what happens in a space-like separated region, then there must be a fact of the matter about it. Not being probabilistic was very important for that. Bell then showed that there cannot be a fact of the matter without there also being some nonlocal means going on in order to account for the QM predictions. It is critical to appreciate the two separate pieces of arguments, how they differ, and how jointly they do lead to some kind of nonlocality. Tim Maudlin has a, now old, book exploring these different levels of nonlocality in quantum mechanics.<p>I recently heard a talk from Tim Maudlin where he mentioned that foliations are the easiest and most natural structures to use to provide nonlocality and, if there is such a thing, maybe there is a clever way of using it to actually communicate and discover the foliation in some sense. He mentioned there is current research on using arrival times which are experimental results outside of the operator formalism, as far as I know. I found an article describing the research:<p><a href="https://www.altpropulsion.com/ftl-quantum-communication-rethinking-the-no-communication-theorem/" rel="nofollow">https://www.altpropulsion.com/ftl-quantum-communication-reth...</a></p>

<p>In terms of quirkiness, how would you rank them? I feel like nonlocality is far less quirkier than saying that all possible outcomes of a measurement happen even though we just see one. Also standard QM has the quirk of being nonlocal. So QM is just quirky.</p>

<p>Since EPR+Bell showed that nature is non-local, it is a feature, not a bug, to be explicit about how non-locality happens. Collapse theories are also explicitly non-local.</p>

<p>In EPR, the setup is that there are two labs doing measurements outside of each other's lights cone. The outcome in one lab allows a perfect prediction of what happens in the other. This means that it is not possible that something random is going on in unless there is some nonlocal coordination between the two. This suggests that there is some actual fact of the matter as to how the experiment will turn out. That is, they argued that QM+locality = extra information beyond the wave function to determine outcomes. Bell then saw Bohm's theory and wondered about getting rid of the nonlocality. Bell showed that QM+extra info determining outcomes = nonlocal.  In short, EPR + Bell shows that if QM predictions are correct (the predictions, not the theory), then there is something nonlocal going on. The lab experiments confirmed this and nature is indeed nonlocal.<p>Thus, there is no local theory that has definite experimental results compatible with what is actually demonstrated in labs. Many worlds, to the extent that one can apply any notion of locality to it, avoids this by not having singular, definitive experimental results (all results happen).</p>

<p>For non-relativistic QM, the QM formalism is provable from Bohmian mechanics, an actual particle theory. BM starts from particles have locations the change continuously in time via a guidance equation using the wave function of the universe. One may choose other theories to explain quantum phenomena, but to say "There is simply no physical machinery to support an objective reality, period." is just false, at least in that realm. As for relativistic QFT, there are plausible pathways using Bohmian ideas as well though nothing as definitive as BM has been firmly established.<p>I would also say that any theory that does not have room to say definitively that I exist is a theory that is obviously contradictory to my experience and is therefore falsified. There has to be room in the theory for at least me. Additionally, I would certainly value much more a theory that has room for the rest of humanity more than one which questions the existence of everyone but me. I am not even sure what the point of a theory would be if it could not account for collaborative science being done.</p>

<p>Crime is often hyper localized. In some areas of some cities, crime may be going up while the overall rate of the city or country is going down. These intensive areas can also change over time. I am not aware of any analysis of the localization of crime and how it changes over time. There are a lot of choices to be made in doing that analysis, but if a reasonable local analysis across a country did that and found that in all localities crime went down, then that would seem reasonable to dismiss that guy's actual experience.  The localization should probably on the neighborhood level, maybe on the order of 1000 people instead of 10000 or more.</p>

<p>pro-communists want a system without competition. Pro-capitalists do want competition or at least no restrictions. People who are practicing capitalists would love to not have competition.<p>Think of a prize race. The people organizing the race and the audience want a highly competitive race. But the racers, if they are in it for the prize, would love to have little to no competition.<p>Artificial restrictions on who can do a thing is not good and it is violence behind, whether it is government or not.<p>Anarcho-capitalists are the true expression of the ideology of free markets.</p>

<p>It was about abusive monopolies where consumers want something different. This is easily fixable by competition. Google is a perfect example of how incredibly easy it is to escape that monopoly. I do it all the time. Imagine what would happen if google started charging a $100 a month for its services. The issue is that the current situation does not conform to what "superior intellectuals" think people ought to do so they want to use violence (government) to force people to live the way they see fit. Yay! All it takes is changing the default. And the anti-monopolists did not even try to do a public awareness campaign of this evil; they went to court (violence) instead of persuasion.<p>I am unaware of what government intervention you are talking about in 1920. I have heard explicitly that the government did nothing by historians and I asked ChatGPT and it had nothing [1]. In that same conversation I also asked it compare Europe versus US in 2008 from an Austrian perspective. The main thesis Austrians have for busts is that of misallocated resources based on false price information whose remedy is reallocation, often through bankruptcy and repurposing of capital goods. It seems that the US was able to have a better reallocation of resources. I am not sure entirely of the mechanism, but at least some of it was allowing some things to fail and some of it might have been the government going in and manually realigning these things (taking over in the short term). It sounded like Europe did not allow for that, either direct intervention or simply allowing things to fail -- the bad businesses limped along as zombies. Europe kind of did the worst of both worlds.<p>As for the US, it also suggests that the Austrians, and I have heard this, cite our extreme debt, and it keeps growing, as a sign of a reckoning to come. Kind of like one can keep pumping sugar in to deal with sugar lows after a high, but eventually the bill comes due. Keynesians and others seem to view the economy as a short-term adjustable kind of thing, a chemical reaction with just the right reagents producing something wonderful. Austrians view it as a lumbering ecology, with things adapting and to the extent adaptation based on truth is present, it gets better. To the extent that distortions and violence happen, not so good. We shall, unfortunately, probably see soon enough unless AI can make a productivity miracle happen.<p>1: <a href="https://chatgpt.com/share/68e3ce42-6e78-8012-8a9c-1d7cff2d6f92" rel="nofollow">https://chatgpt.com/share/68e3ce42-6e78-8012-8a9c-1d7cff2d6f...</a></p>
