<p>I agree with your "sensationalism is bad" take; especially as meaningful, non-incendiary comments now often get quickly downvoted for viewpoint, not tone (IMO downvoting should cost 0.1-0.3 karma). But not with "nothing to see in CB gold holdings fluctuations" view:<p>R1. But central bank gold holdings are rising organically, and partially at the expense of US treasuries. CB gold holdings have been dropping for 35 years, until about 2015. The price rise of gold from 2005 to 2015 did not reverse this trend. From 2015 to 2019 gold price did not rise, but reported holdings did. The recent doubling of the gold price muddies things a little, but the trend is clear.<p>R3. Reported gold purchases have trended down in 2025 and 2026, probably due to price doubling. But they are still positive. Emerging markets did not sell into this strength to build up more liquid holdings (UST) as more effective tools to support their economies against future malaise. Even "trending down" part is muddy, too, because some countries CB do not report it. China, an elephant in the room, started better obfuscating its holdings, including gold, since COVID.<p>R4. Yes. Gold owned by CB strognly trended down since 1980. That trend stopped in 2005 and reversed somewhere between 2005 and 2015. And likely accelerated in the last few years.<p>As a side note, I personally see USTs losing dominance as a reserve asset as a good thing. USG needs some checks on its spending, and world being willing to buy long dated treasuries at below inflation rates incentivizes the "we do not need to solve real problems, we can just print more money" mindset. My 2c.</p>

<p>I do not think so. The Windows - OS/2 war was a big fight that Microsoft won on merits. Windows 95 was revolutionary at the time, folks queued at the malls on the release day to get it, bugs and all.<p>They fought the compiler wars with real engineering, giving Borland a run for the money. Different people have different opinions about Visual Studio. As a Linux user since 0.9 I did not like its architecture and focus on GUI at the expense of everything else, but I still saw it as a consistent framework done by excellent engineers. And so on.</p>

<p>Microsoft lost its way much earlier than 4 years ago. It abused users at the time of Netscape wars and forcing Internet Explorer down people's throats.<p>But they hit an infinite gold mine with government adoption and for the last 30 years no amount of bad engineering was able to shake off government use.<p>Windows 11 is bad? Yes, but did you try Microsoft Teams? The only way to force Microsoft into "users matter" engineering is to get govvies off it. My 2c.</p>

<p>PhD programs are very different. The environment Karpathy describes is fairly similar to what I saw as a math PhD in a good school, but not an ivy. My theoretical physics PhD friends had the same setup as I had, but experimentals lived in a different world, long hours in the lab every day, including weekends.<p>My advisor was well established, tenured prof with a number of students. I had to teach, but the effort was light. We taught large, basic courses that are boring for tenured profs. We usually requested the same 1-2 classes to teach and after the first round had all the materials (homework, quizzes, etc.) and could teach on autopilot. University gave us undergrad graders to grade assignments but I never used them since I wanted to see what my students wrote. Which is a testament that the load was light; if I was drowning I would use all free help I could.<p>But there was a cult of academia. "Get an academic job or you are a loser" mentality was prevalent. My advisor was disappointed, but OK when I decided to go into industry after PhD, but a friend's (Physics PhD from Harvard, CEO of a profitable startup now) advisor does not talk to him anymore because he did not stay in academia.<p>And I only realized long after finishing my PhD how incredibly lonely PhD path is. You live in your bubble for years, with minimal interactions outside a few other folks at the same grad school. Stipend was enough for basic living, but not much else. No good vacations, ski trips with friends, etc. And a few somewhat creepy characters that grow in this lifestyle. This is all surmountable, but the mental toughness required is certainly something to keep in mind. I did not have that mental toughness, but was an introvert, which helped a lot. But looking back I see that I also could have gone off the rails. My 2c.</p>

<p>In some age groups/environments, sure; but not in general. And if folks crave interaction they want it to be deeper than a surface level.<p>That's not saying you should not try, but learn to recognize early signs of folks not being interested and don't push it.</p>

<p>Register your own domain, use a third-party provider to handle actual sending and receiving (I use proton, which makes the setup very easy), forward your Gmail to your personal domain address and as renewals and reminders come in switch your email on services to your personal domain.<p>After a year or two losing Gmail becomes an inconvenience; after a few more years it is nothing. As everything is now on your own domain name you can switch providers without affecting anything.<p>That's what I did about 5 years ago and my only regret is not doing it earlier.</p>

<p>> N1 failure is attributed mostly to Korolev - Glushko rivalry that resulted in N1 lacking engines in time.<p>That is a viable version. But I think this was one of the problems and there were plenty of others. While Chertok does point to the engines as a major problem, he also admits that the whole system became way too complex to succeed.<p>His description of electrical components (for which IIRC he was the chief engineer) and checkouts is telling. He also describes the feeling of "good envy" as the Russian engineers were listening in on comms between the Earth and the Apollo 13 during its mission. Which drove home the point of how much advantage US had, at least in electronic, and how powerful it was for its successful lunar program.<p>> It's all a sad story of unchecked emotions leading to monumental waste.<p>I have a softer view. Both Korolev and Glushko wanted their own leadership, which is normal. Korolev ran his shop in a dictatorial fashion, as that was the only way he could operate efficiently. Which is also fine and can produce spectacular results (and it did early on). But it comes with its own risks, including motivating strong leaders to branch out. I would not call it unchecked emotions that Glushko, <i>after many years at OKB-1</i> went to run his own projects.<p>Living in a someone's shadow while under his dictatorial control is not for everyone. I can see the arguments for both sides. My 2c.</p>

<p>> inexact quote: "You know, we're throwing towns into the sky" related to the early mishaps of R-7 program development<p>I have not looked at the source (in Russian) for several years; now that I am curious I will check at home tonight. But as far as I remember "we are shooting towns into the sky" remark was <i>not</i> in reference to the R-7, but in reference to N1-L3, a hellishly expensive competitor to the Apollo manned Moon mission rocket. The meaning of the phrase was that each and every test should be taken extremely seriously as the cost of each flight is comparable to the cost of building a new city.<p>R-7 was developed much earlier when Korolev and his team at OKB-1 were iterating rapidly on much cheaper models that were primarily funded as rockets for strategic thermonuclear strike warheads. The civilian (Sputnik and later Gagarin) flights were an offshoot of that and were small enough that it happened as a side project. R-7 was a comparatively simple and cheap design, which may be why that family became a workhorse from the late 50s to carrying crews to the ISS. And the super expensive N1-L3 was a stillborn.<p>That's my recollection, need to recheck the sources.</p>

<p>Not an expert, but main challenges with laser coherency are present when shaping the <i>output</i> using multiple transmitters.<p>For lidar you transmit a pulse from a single source and <i>receive</i> its reflection at multiple points.

<p>This, as written, is just an idea. Lots of forward looking statements on how the EU must do this and that and no explicit promise to offer funding to all affected US scientists. Not even many details on the funding. Is it the same funding? Equivalent funding? Some funding (how much? what are the conditions? etc.).<p>Not claiming that this will not entice anyone over, but it is far, far different from the original claim. Sorry.</p>

<p>> German universities are now telling any US researcher who looses their funding that they will be funded at a Germany university<p>Is this true? Is there a link to the policy?

<p>They never actually put a full effort into building a consumer oriented economy.<p>The authorities would say something about a new food program or a housing program but only as motivational goals.

<p>The counter argument to that is in the age of the social media there is no need to take to the streets to show that there is dissent. Everyone the folks on the street could reach will know about the dissent anyway.<p>Motivating other people to take a stand -- I do not think this is true either. A fraction of the folks who would support the issue regardless may join the protest on the street. But that would be those who support the issue already.<p>Change comes from the ballot box. Enough people in the street might influence the next election (sometimes for the issue they are advocating; sometimes in the opposite direction). But 6+ months from the next election the effect I suspect is small. My 2c.</p>

<p>The cited rationale is a perfectly reasonable take.<p>But most of the world is in the same boat of "large budget deficits and growing government debt".

At least in the US, that path has been virtually unavoidable after the fiscal spending by G.W. Bush on the 9/11 wars and fully set in stone after 2008 subprime crisis.
