I don't engage with people who think we should delete everything to "save the environment" because their grasp of the issue is so pointedly myopic that their solution to saving the environment is destroying humanity.
"We keep everything in data centers and it's so terrible." Yes. It is. But it's an array of issues that are extremely solvable and don't require the purposeful destruction of decades of human creativity.
Analogizing to archives of physical stuff and libraries is bullshit. The things they preserve physically degrade and take up far more space.
