I can empathize with this opinion, but deep in me it feels (I am not saying it is) wrong. Maybe I love books too much. My fear is spending too much time optimizing life instead of living, so to say. The value of Anki is clear, but I wonder how many hours it takes to create that list. Maybe that is time when I could be reading another book on the same topic, for example. Or I am rationalizing because I find it annoying to enter things in Anki (even a csv file) :) The compromise I found is: if you own a lot of physical books, underlining (normally or with small vertical lines on the side) makes it easy to go back and remember the important facts. I also write my reaction to some sentences on the margin. All of this helps me remember better, and it makes it easier to get back to it later to get the main points. It seems to work well enough for now.
