A 100- and 500- year plan is ludicrous on it's face. They don't even credibly hit their 5 year plans a lot of the time. The idea of planning something so large and complex so far into the future seems like wishful thinking at best.

“In preparing for battle I have always found that plans are useless, but planning is indispensable.” — Dwight D. Eisenhower "No plan survives the first shot of the battle". So, sure, the plans will likely not survive in any detail even a decade from now. But the fact that they are making plans, attempting to understand the considerations of those future generations, understand what strategic goals need to be worked o…

> And notice that the US is not now trying to return manufacturing home because of long-term plans, but because the people noticed that the bargain of cheap goods from China doesn't mean much when you exported the job

Most of those jobs outside of a few narrow categories were lost to automation. We make more steel, aircrafts, and cars than ever but with far fewer people.

China's history of planning has led to tons of misallocation of resources, and I'm not sure I'd want to emulate that.

One of the interesting possibilities for the Fermi Paradox is the fact that we've wiped out the readily accessible deposits of iron, coal, oil, etc. A second go at the industrial revolution would be much harder, if we regressed that far.

Coal, yes. Iron, wouldn't the iron we moved to the surface be even more accessible? We didn't destroy it, just rearranged and concentrated it?

Stone coal could be, at least partially, substituted by charcoal - and often was in the past, where reachable underground coal reserves were not available.

I've seen exactly blue-collars workers arguing for impossibility: it's hard enough to do with modern technology ("I know it first-hand!"), how would you even do it without it?

That’s perhaps a testament to our dependence on modern machinery, if the skills did exist once.

It's fairly simple to construct a way to see your own face. All you need is a high-grade color LCD or OLED display, a high-resolution digital camera, a power source, a few controls and a logic board. Too bad none of this was available before 2010, those poor ancients must have always wondered what they looked like.

very little from the past survives through to today. I don't think there is any record of this device existing other than the device itself, and mention of it after its discovery in the early 1900s. to some that will be proof that it is not truly an ancient device, and I think that is hogwash. most things just don't last that long, especially paper, which is where mention of the device would be found, if it ever is f…

I don’t doubt it’s ancient. I’m not skeptic from that POV. I do find it curious that such an object would be exist but not have some fanfare around it. I’m sure there’s an explanation that eludes me. Could have been developed in some secrecy for example because it have the people who used it some advantage?

Thinking of the most elaborate clockwork built today, those quarter million dollar wristwatches, there isn’t much written about them, maybe a youtube sizzle reel at most. Their customer base is small and they have little reason to document the inner-workings.

Could be this mechanism was just an exquisite commission for a wealthy dude to keep on his boat.

Did I miss that he finished the mechanism? From what I've seen he went into hiatus and has been only posting ClickSpring "clips" for a while now?

He hasn’t completely finished his reconstruction, but he hasn’t entirely been on a hiatus either. He co–authored a paper on the calendar ring of the mechanism: https://bhi.co.uk/wp-content/uploads/2020/12/BHI-Antikythera... But he hasn’t made many videos the last year or two.

Some of his videos are only available via Patreon.

Japan has very low quality iron ores. Yet they turned out (arguably) the best steel swords in the world. Constraints don't always lead to bad outcomes.

The pre-modern/medieval Japanese iron industry was actually quite massive! We went to a museum in Izumo and there was a nice map showing the are in ancient times and now and the difference was pretty stark - there were just swamp where the Izumo city is today and the local lake Shinji was like twice as big as today.

All the new land and end of the swamps is apparently the result of hundreds of years of iron ore mining in the nearby mountains. So even with primitive means and shitty ore, if you need the material and go at it for centuries, you can achieve substantial results. Not to mention reclaim some land as a result. :)

Also in related (but much more recent development) there were coal mines in Japan mining from under the seabed via tiny islands!

Hashima is the most extreme example, basically a piece of barely dry rock that has been converted to a concrete city housing many thousands of workers and their families: https://en.wikipedia.org/wiki/Hashima_Island

But there were other such mines, some of the local ones even connected to Hashima via the underground works!

That's not a problem of the craft however, it's a problem of the culture. We are perfectly capable of writing native GUIs, and we have powerful tools for it as well. QTDesigner comes to mind as a well known example. The problem is, about 12 years ago, application design went through a gameification and "toy-i-fication" phase, from which it has yet to recover, because suddenly, everything had to look like it was desig…

It is a culture problem, but it goes back before phones and Javascript. Even before that, application design was usually terrible. Apps were almost universally ugly. Developers just aren't very good at it; it's not in their skill sets. They're good at making apps fast and small, but not at making them usable. Rare companies would hire separate designers, and the apps could be functional and attractive, but they were…

I wonder where the notion that productivity software should be “attractive” came from. Were whole businesses not built on VisiCalc?

The registers at B&H photo in NYC appear to be some DOS terminal system, but the employees know the keyboard shortcuts by muscle memory and the interface’s reaction time is instantaneous. If that’s not good software I don’t know what is.

Japan definitely produced some of the most beautiful looking swords, and they are extremely impressive given the quality of iron they are forged out of, but I don't think any sane person would choose one to take into battle given any other option.

I am confused. Are you saying that the quality of the iron makes them shit swords, or that guns are better than swords?

You jest, but I've heard a tale from a local engineering college: they regularly give to the graduating-year students a task to design some system which, after you remove all the fancy wordings, is basically insides of a toilet cistern/tank. Year after year, the students keep producing astonishingly convoluted designs.

A sword is a tiny amount of metal compared to, say, a steam engine. Or a battleship.
