@Gargron I do think this will be true over generational time scales & I dont necessarily think that physical media would always be the more robust option. Both have pros and cons.
The recording of audio & video is relatively new in the last 100 years or so. Think about what that body of work will be in 500, 1,000 or even 10,000 years from now, assuming humanity persists. How much content will exist? It would take lifetimes to sort through. Will anyone in the year 12023 listen to The Beatles?
