Sure, “no man sets foot in the same river twice”, but that does nothing to argue against the preservation of cultural items.
Take music, for instance. I never feel the same way the second time listening to a song as I did the first time, but that doesn’t make the music less special or change anything about it at all, and it certainly does nothing to advance a hypothetical argument that music shouldn’t be recorded or that the recordings of it shouldn’t be preserved for future enjoyment or different audiences.
Because they got tired of paying for the whiny engineers that would have to implement the failsafe and so they fired them all.
