It seems to me, at least when it comes to quantum mechanics, "information" has become the most basic unit. Like, quantum entanglement works to the point that information is extracted, and one can even revert certain things by making sure the information is destroyed. Same with the discussion about black hole evaporation etc, where the hinging point was that a black hole would destroy any information falling into it. My question would be, is there any material (books, papers) discussing this? I find this whole subject very tantalizing, maybe because I work in machine learning where information is the basic unit too. EDIT: Just to make sure what I'm asking, I'm not too interested in the specific black hole or quantum eraser experiments, but rather a slightly more "philosophical" discussion on what this shift might glean into physical "reality".
