I am glad to hear you are invested in Zettelkasten and it is effective for you. But I wouldn’t characterize people who don’t like or use it as impatient or oblivious. Luhmann’s mindset isn’t universal, just as yours isn’t… or mine… or @kewms, @meowky, etc.
That is much of why we don’t try to develop DEVONthink or DEVONthink To Go into a bespoke Zettel application. But you should also take note we aren’t developing our apps specifically for Johnny Decimal, GTD, PARA, or any other particular system. Do we provide flexibility in our apps to help accommodate those things? Sure, to some degree or another. But I’d say our largest contributions in supporting such systems are our automation tech, allowing people to shape their environment in deeper ways than many apps do (or can) and the deep linking. Between those two, many things become possible.
