I have been a playboy in Notion lol. I spend a lot of time trying to document my finding and knowledge and that has been pretty well journey so far. I feel that document management and also handling and processing knowledge as we acquire it and then filter the gist of it is kind of human life. And yes we do need AI to handle this in near future. Just not sure how all of this would connect dots like each person has different way to manage the data, interpret it's meaning etc. So we have plenty of things left in to cover over.
The trick is to handle the labeling of the information at a structured base level (semi-manual model or automated) so that it doesn't matter where it is, it can be found. The interpretation comes down to human (or AI) however, as always.
