I do find note-taking to be a useful way to learn and remember things. Usually if I'm studying something seriously I'll make notes using pen and paper, and then later consolidate them and synthesize them into an Obsidian vault.

But I admit that the Zettelkasten method has had marginal benefit for me, possibly because I'm not working that way all day every day; and simply copying and pasting articles from the web into your knowledge base isn't going to accomplish much of anything for anybody.
