Remember children, nuking countries is bad, m'kay?
Sorry for the "radio silence" these past few days. I had some more thoughts on the "loss of technology" argument we had a while back, and at this point I might be beating on a dead horse. A few days back I was browsing Alibaba to look for manufacturers to custom make my engine parts, and noticed that other than CNC, old methods like lost-wax casting is still used today. Same with forging, welding, milling so on so forth.
Then I looked back at the Rocketdyne F-1, turns out most of the parts are also made with methods that are still used today, problem is, we forgot "how exactly". It's like making beef wellington, you have a veteran chef who have made those for years and developed his own tricks to get the job done effectively and efficiently, now give the same gear and supplies used by the veteran chef to a new chef, he wouldn't know how to make a beef wellington as good or at all even with the exact same equipment provided. Previously I thought everything was forgotten.
This contributes towards another unresolved problem with the argument that was our attitude towards manufacturing. So far there are three categories; past, present and future.
Past methods are forgotten because they were unfeasible for modern day large scale applications, say the elliptical wing.
Present methods are usually composed of past methods that are still very useful today, like many subtractive manufacturing methods.
Future methods are more advanced approaches like vacuum induction casting and computerized numeric machining control.
Right now we're gonna worry about the past and future, since that's what we're the most worried about, and since a certain individual insists laziness is the death of tech, and I'm having second thoughts. We have two approaches, that is preserving methodology and advancing methodology.
The preservation of methodology; if use of a methodology is obscure and limited (like the rocketdyne F-1 engine), it must be well documented to give future mantle takers an idea of how said method is carried out (something the engineers working on the Saturn V done poorly). If use of a methodology is widespread but is about to be replaced by a superior alteration, it must too be well documented or if possible, practiced (for example blacksmithing and spinning).
Our willingness to preserve a method is strictly dictated by our respect for it. We lost the know-how to build the F-1 because of our pride, our complacency, we were so full of ourselves when we beat the Reds that we neglected to remember, we disrespected it. Doesn't help that the higher ups cancelled or outright refused future deep space manned missions after Apollo.
The advancement of methodology; this sector strictly depends on our intelligence and past experience. We can't have CNC without NC, we can't have vacuum casting without die casting and we definitely can't advance without the geniuses down at R&D.
Advancement is innovation, innovation takes time, time needs passion. When you're passionate about something, being lazy will be the last thing on your mind. Laziness as a tech killer just doesn't add up.
Then there is war, which is caused by hatred.
