Libgen is a civilizational project that should be endorsed, not prosecuted. I hope one day people will look at it and think how stupid we were today to shun the largest collection of literary works in human history.
Libgen turns into a problem when you have a company developing generative AI with it, either giving money to GPU manufacturers or themselves with paid services (see OpenAI)
Personally, I strongly believe that the aesthetic skills of humanity are one of our most advanced faculties — we are nowhere close to replacing them with fully-automated output, AGI or no.
