When all the people in the world die out, all the cities and the villages would be abandoned and become barren wasteland, but what will become of the Internet? Would there still be "activity" in the cloud? Would it be a "wasteland" too? Or would it even be any different than what it is now? What if all the power runs out? Would the Internet still "exist" then, with neither observers nor an entrance?
Also, will future civilisations be able to access our cloud, and would they use it the same way we treat fossils and historical artifacts we find nowadays? What if there have been such inventions in the past, but we just have not unearthed or discovered them yet?
Also, how much of our "false information" will the future civilisations take as true? Heck, how much false information are we already—wrongly—taking as true?
