I agree with the part where taking notes lets us structure our ideas and helps us remember. However, here's one principle that I found very useful: note-taking should be structured in such a way that you _encounter_ notes that you took previously. This is part of the idea behind Roam's backlinks, but I think no technology by itself will help here. The problem is having the correct approach: it should be possible to list notes on a topic, and they should be reviewed from time to time to see if they are relevant or not. This way, ideas which were noted down can be reviewed, kept track of, and pruned -- just seeing the title of a note is more than enough for this. I've been doing that for more than half a year on various topics -- world locations, news, films and books I've seen/read, CS papers, research ideas -- and the results are great: I can remember more and I call recall and describe my memories more fluidly. What's important is that note-taking isn't the only way that "old" ideas can be re-encountered. If you want to remember information about the world, just take a look at the world map from time to time, point to places and think about what you want to remember.
