Over 2000 years ago a chap called Philodemus sits in the library of a luxurious villa owned by a rich guy who likes collecting art and writing. He writes his thoughts on pleasure, and the relationship between the quantity of something and the pleasure that might derive from it. The scroll goes on the shelves with the others. He writes lots. At some point later the villa is covered by lava from mt vesuvius. 2000 years…
I have too wild imagination sometimes. I picture him with a shocked look on his face, similar to what one of the modern 'thinkers' would have if they forgot to clear their browser history and somehow someone restored it in the future. "You recovered... uh... everything?"
And of course, rm just unlinks, doesn’t actually delete, so even going a step further and recovering deleted content is hardly magic.
This is more like if, sometime in the future, they somehow successfully reconstructed a snapshot of our computers’ volatile memory by examining the power supply, or something ridiculous like that.
