That could be part of it. But I think survivor bias generally gets much more credit as an explanation than it deserves, and I strongly doubt that older generations of tools would have been designed like modern tools even if, say, simulation software had been available then.
It could be just relentless pressure to reduce costs, after the people who knew why it should be done a certain way had all retired, and a customer base that changed into one that either didn't know how to recognize quality, or valued it less.
Maybe we can do without heat-treating the surface? Maybe just give a quick grind instead of hand scraping the ways? Maybe outsource the castings instead of doing them in-house using the process we'd honed over decades?
A rock the size of a human head (or, say, a container of seawater) has just as many electrons, protons, neutrons, photons, and other particles going about their business and doing their little dance, following the same equations of motion as our brains do. They're certainly doing it in different ways, but if you're just looking for complexity, there's no shortage of it. The rock might lack some macroscopic structural change over human timescales, but definitely not the seawater.
I think if you take the perspective that the human brain is conscious but not a brain-sized container of seawater, you need to then look carefully for distinctions between them. "Information processing" or "response to environment" is probably not good enough; the seawater is actually doing all of those, with a unique reaction to any possible input, so you'd have to be more specific.
Probably the only recourse you could look for to make the distinction is to say the brain embeds particular mathematical patterns that the seawater doesn't, such as a compact, stored representation of its environment (or its history of inputs), or a future-looking planning algorithm, or both. I personally take this view (I think of qualia, like "the appearance of a red apple", is just precisely what it feels like to read from the buffered [R,G,B] memory array in my head, filtered through image-recognition networks).
But then if you put your hopes on consciousness originating from those mathematical functions, you have to admit that any analogous expression of those functions in other systems would also be conscious, such as animals and robots.
And worse, once you start thinking about math and how flexible it is, how information is in the eye of the beholder and almost any system that follows certain rules can embed almost any mathematical computation, just like illegible scratches to me are information-rich writing to you, you might have to circle back and that there could be very analogous computations going on inside rocks and seawater. And that brings us back full-circle.
Not sure it's a fair analogy. Even while they were being deceitful, the Soviet Union seems to have at least invested a serious effort into tackling the problem head-on.
Yes, but that also comes with the notion that a wealthy family can become poor by moving to a higher-cost area, or a poor family can become wealthy by moving to a lower-cost area; ie, someone can sell a small house in the Bay area and buy a manor estate in the countryside.
There's nothing wrong with that notion, but some will find it odd that, before that transaction happens, a family owning an upscale countryside home is wealthier than a family owning a cramped Bay area home, but after that move happens, the family that moved in from the Bay area is now the wealthier one.
It means that merely having the option to sell your home and buy a countryside manor doesn't make you wealthy until you actually follow through with it.
There's so many times that an ostensibly international website has rejected me because I don't have a US-formatted numerical zip code. Even when they have a country field.
Even for Latin, apparently Ecclesiastical (Church) Latin, which is more familiar to most people today, differs in pronunciation from Classical Latin. For example, Ecclesiastical Latin uses a soft 'c', where the ancient Romans would have used a hard 'c' -- Cicero's name would have been pronounced like "keekero" in his day, whereas most people now think of him as "Sissero". Although the Roman empire was large and diverse enough that Latin probably had quite a variety of dialects and maybe Ecclesiastical Latin was one of them.
Hebrew is an unusual case because, like Latin, it was mostly a dead language that for centuries only continued to be used in religious and a few other contexts. It was revived in the 19th century. Because of its long period of cryostasis the parts that were preserved probably haven't changed that much, although necessarily it's expanded greatly into a living language.
Practically, the fastest and easiest way would be to turn a good cylinder and measure the diameter at several points (or roll on a surface plane) to make sure it's not tapered, because the face will sit square to the sides even if the axis cutting the face is concave.
More fundamentally though, you can use a similar method -- start with a surface plate, and make three almost-90-degree right angles. Label them A, B, and C.
Scrape A and B so they perfectly mate with each other while they sit flat on the surface plate. They might be something like 89 degrees and 91 degrees, so scrape C to be a copy of B, and then mate it with B. From that you can tell if they're both acute or obtuse, do the correction, and repeat.
It wasn't nearly so easy. Dan hand-scraped in several surfaces on the lathe; for example the headstock, to get the axis parallel to the ways, and so on.
The grandparent's label of "central planning" seems to encompass almost any possible policy that deviates from a completely free market. I don't think any mainstream economics, other than caricatures, supports the idea that any possible economic policy that isn't a completely free market doesn't work.
Wait, who was proposing or even talking about central planning in this thread? I think you're the first. I was going to propose we allocate resources by sacrificing goats to the thirteen forgotten gods of the underworld, and then interpret their bones for wisdom.
I just wanted to clarify that when you said higher prices discourage those with lower needs, what you really meant is that it discourages those with lower means-weighted-needs. Which is to say, it discourages the desperate-but-poor, rebalancing demand toward the less-desperate-but-more-wealthy.
Why do the design in the US? Chinese engineers are doing great designs themselves, and for less than American salaries... And they can visit right there on the factory floor, talking to the manufacturers directly about how to make their designs, in the same time zone and the same language...
Are US engineers imagining the same ideas about being irreplaceable that an earlier generation of American machinists, tool-and-die experts, and manufacturing workers also did?
