To a large extent it probably depends on the nature of your work. I found that once I transitioned to more horizontal roles at work, taking good, organized notes became more essential. I don't think the specific system matters all that much though. The recent popularity of Zettelkasten is not really about systems per se as much as it is about recognizing that being able to refer to other things, or tell what other things refer to the current thing, is valuable. For people who just sort their e-mails into Outlook folders and have never thought more deeply about any of this, it is often a helpful shift in one's mental model.
