I disagree. I think it's about pivot time, not having a warmed up stable of skilled workers just in case. Nature never optimizes for that and it shouldn't. We should lazy-load that skillset if and when it's necessary. We have writing to carry knowledge forward. Also, video and other media. People are smart and I'm sure a large cohort could be assembled with the right amount of money in fairly short order. As long as that's cheaper than keeping a battalion ready just in case, then I'd argue it's the "correct" way to approach it.
