I think in reality I would milk it for personal gain, but in this hypothetical thought experiment I’d also like to imagine putting it into public domain.
Yes we would certainly see a lot of trash, but I’d imagine that it would also lead to a lot of creativity. We really are hampered by the insanely long copyright durations.
Sherlock Holmes for example has been part of general culture for a long time, and yet the last novel only became public domain 2023. Considering how much the world changed between now and 1927 (when it was published) it really doesn’t make sense. And the argument for copyright that invention needs to pay also falls flat, when it extends so long even after the authors death.
