       | Same with technological information. The way you keep information

       | bricks, because a lot of people in a lot of factories make bricks

       | and once the special circumstances which made it viable has ended
       | people forgot how to build it. Who cares?

       | If someone wants a rocket they can design one for themselves. And
       | turns out, they do. And those newly designed rockets are better
       | for them. Not better in some tech spec sense, but better suited

       | Easy answer: Her personal zeitgeist. The author seems to focus on
       | the lyrical meaning of the song being the root cause for her
       | emotion. But her reaction is likely far more complex than "satire
       | of communism" but a time capsule or snap shot of memories and
       | emotions of her world when she heard this song. It not only
       | recalls memories of a painful part of her life but also the
       | pleasant parts: friends, relations, family, things and places
       | which are long gone; A temporal marker to a place which she
       | cannot travel to.
       | 
       | Of course the author kind of explains this in the next paragraph,
       | but then seemingly backtracks to her interpretation of the
       | lyrics: "We will never be able to truly understand or feel how
       | the satire hit under the weight of an oppressive communist
       | regime." I highly doubt it was only about the weight of an
       | oppressive communist regime.
       | 
       | When I hear "eye of the tiger" I can get a bit emotional. It has
       | nothing to do with "Rising up to the challenge" or the band
       | Survivor but the whole of the period in which I heard the song.
       | It brings back a simpler time: childhood bedroom, my father was
       | still alive, the joy of being a kid and discovering rock music.
       | It's so much more than the subject of the song and lyrics...

       | when in reality 2020 alone had plenty of reasons for her to feel

       | 
       | First, we didn't really forget "greek fire" or "roman concrete"
       | exactly. We don't know what the formula for "greek fire" was
       | exactly because it wasn't recorded. But in modern times we have
       | an amazing chemistry and can come up with a hundred formulas for
       | napalm -- we just don't know which of those matches "greek fire".
       | Nothing was lost but the association between a formula we almost
       | certainly know and a name.
       | 
       | Same goes for roman concrete. We know far more about concrete
       | than the Romans did. We just don't bother to engineer everything
       | to last forever, because that costs money and has little point to
       | it a lot of the time. Yes, some buildings are works of art, but
       | many things just have a function to fulfill, which is often
       | temporary. Nobody is sad that the millions of mass-made soviet
       | residential crappy buildings aren't still as good as new. If they
       | were made to a better standard they'd still be ugly cookie cutter
       | things.
       | 
       | And I'd say the same goes for the Saturn V. We didn't forget
       | material science or heat shielding. We launch plenty rockets and
       | even landed car sized robots on Mars -- that required excellent
       | understanding of heat shielding. If we had any reason to build a

         | Unfortunately...
         | 
         | 1. There's no "we". i.e. the entities choosing concrete
         | mixtures and other construction technology do not typically
         | share interests with the people / organizations which inhabit
         | the buildings, except in some very abstract roundabout sense.
         | Which is part of the reason why
         | 
         | 2. Concrete construction is usually not engineered to last even
         | a few centuries, let alone "forever". In fact, it is often so
         | poorly engineered (or one might argue: misengineered) that it
         | won't last even a single century, or less than that. Because
         | the principle of costing less money tends to be taken all the
         | way to the point of just barely passing regulatory constraints.
         | 
         | 3. ... and those regulatory constraints are often quite
         | lacking. I live in Israel, and a constructor is not even
         | required to guarantee that their building will not-collapse
         | beyond 7 years' time.
         | 
         | 4. Actually, a lot of the mass-made soviet-era residential
         | buildings are very well made and almost as good as new (well,
         | considering how they often weren't so great when new). This
         | depends on the specific country, region, period of construction
