On Revivals/Ship of Theseus

Apparently, there is still data from the Voyager missions in the 70s that have never been analyzed. Information overload is actually underload, when you consider the potential for discoverable information there. Why make anything new when you haven't gone through the old stuff yet?

Older genres of music get pushed to the margins by too much New, when in fact their own New is lying dormant within them, waiting to be discovered by people that were never aware of it.

Rock isn't yet a relic, but it's getting there.

Revivals tend to be retro treatments, rather than an experience of the work in its original form. I have seen questions asked on Quora whether Rock will be revived. It will naturally evolve like all genres, but over different time scales. The armatures that were there at the time would need to be revived, namely structured music education and a music industry. But even if you built out the past to look exactly like the present, would the future repeat it exactly?

This calls to mind the Ship of Theseus myth. If a "ship" is rebuilt from scratch, is the essence of the original ship in the copy?
