In February 1942, R. Bradley, a British Officer in the Royal artillery in World War II was captured and then held prisoner by Japanese in Singapore. Their camp was remote, supplies were almost non-existent, and they were treated roughly as POWs; when they rebelled they were locked in a confinement shed without food.

"Though these "clothes" are obviously hideous, the technology's potential is staggering. What happens when 3D printing allows for (normal) looking clothes to be printed at the click of a button? The implications on the labor markets and foreign production are staggering. Instead of having workers in China stitching together shirts emblazoned with wolves and crying eagles, we can have computers do the work instead, leaving workers more time to create poisonous children's toys and toxic overalls."

But they were tinkerers, too. Together with some other POWs in his camp, Bradley stole hand tools from the Japanese soldiers and from these bits and pieces he transformed scrap metal into a miniature lathe.

During the two years of their interment the lathe remade the tools -- like taps and dies -- which were first used to create it. A lather has those self-reproductive qualities.
-
Over years of tinkering, Gingery was able to bootstrap a full-bore machine shop from alley scraps. He made rough tools that made better tools, which then made tools good enough to make real stuff.
-
In its center was a coffee can of smoldering BBQ charcoal. Inside the can of charcoal was a small ceramic crucible into which he threw scrap aluminum – cans, etc. Gingery forced air into this crude furnace via a fan, burning the charcoal with enough heat to melt the aluminum. He poured the molten metal into a mold of wet sand carved out in the shape he wanted. When the cast was cool he had a workable metal holding plate, which became the heart of a homemade lathe. Other lathe parts were cast. He finished these rough parts with hand tools. His one “cheat” was adding a used electric motor – although it is not impossible to imagine a wind or water powered version.
-
When the rough lathe was up and running he used it to turn out the parts for a drill press. With the drill press and lathe operating he constantly reworked pieces of the lathe itself, replacing parts with improved versions. In this way, his tiny machine shop was an upcreation device, capable of generating higher a machine of precision than itself.
-
Gingery recapitulated the evolution of technology, the great pattern by which simple tools create more complex tools and so on infinitum. This expansion of upcreation power is the means by which an entire culture lifts itself out of mud by pulling up on its bootstraps.

Yet is it obvious this little demonstration is not pure. As a way to make your own machine tools, Gingerys’ plans are fine and dandy. He uses cast off washing machine motors and other junkyard scrap parts to grow a fairly robust machine shop. But as an example of relaunching a technological society in a kind of Robinson Crusoe maneuver – landing somewhere and starting civilization up -- it’s a cheat because in this latter game you don’t get to start with discarded aluminum cans, scavenged nuts and bolts, old electric motors and waste sheet metal.
-
To really navigate the minimum bootstrap path through the industrial web, you’d have to start with finding your own ore, mining and refining it with primitive tools, firing up bricks, rolling out sheet metal, developing screws and bolts by hand – all just to get you to the point where you’d have enough tools and materials to make the simple 5-gallon bucket foundry that Dave Gingery started with.

Select at random any one of the many thousands items within the reach of where you now sit. None of them could exist without many of the others around it. No technology is an island.

Let’s take a very sophisticated item: one web page. A web page relies on perhaps a hundred thousand other inventions, all needed for its birth and continued existence. There is no web page anywhere without the inventions of HTML code, without computer programming, without LEDs or cathode ray tubes, without solid state computer chips, without telephone lines, without long-distance signal repeaters, without electrical generators, without high-speed turbines, without stainless steel, iron smelters, and control of fire. None of these concrete inventions would exist without the elemental inventions of writing, of an alphabet, of hypertext links, of indexes, catalogs, archives, libraries and the scientific method itself. To recapitulate a web page you have to re-create all these other functions. You might as well remake modern society.

This is why restarting a sophisticated society after a devastating setback is so hard. Without all the adjacent items in a given ecological bundle, a single technology can have no effect

The conundrum of disaster relief is a testimony to this deep interdependency: one needs roads to bring petrol but petrol to clear roads, medicines to heal people, but healthy people to dispense medicines, communications to enable organization but organization to restore communications. We see the interdependent platform of technology primarily when it breaks down.
-
This is also the explanation of why we should not confuse a good clear view of the future with a short distance. We can see the perfect outlines of where technology is going, but we tend to overestimate how soon it will come. Usually the delay (in our eager eyes) is due to the invisible ecology of other needed technologies that aren’t ready yet.

Classic example that's relatable to nerds: Virtual Reality. In the '90's, the graphics tech wasn't close to where it needed to be. Also, ram prices and other hardware limitations (speed) made implementing it in any serious way a joke. Now, of course, the Oculus Rift is a consumer good. We don't call stuff "VR" anymore (as a buzzword), we just know we can buy a cool attachment that makes everything 3D.

The invention will hang suspended in the future for many years, not coming any closer the now. Then when the ignored co-technologies are in place it will appear in our lives in a sudden, with much surprise and applause for its unexpected appearance.

"A favorite fantasy game for engineers is to imagine how they might re-invent essential technology from scratch. If you were stranded on an island, or left behind after Armageddon, and you needed to make your own blade, say, or a book, maybe a pair of working radios, what would it take to forge iron, make paper, or create electricity?"
