I guess it depends on what you do. For huge creative endeavours, which work by emergent layers and constant sense-making, it is indeed a game-changer. I would never want to go back to anything that does not allow flexible linking.
If your work functions more in fixated areas, then folders absolutely represent a more readily accessible paradigm. Even though I would venture that link-based thinking, that is, working through analogies and not categories, is the natural way of the human mind.
It’s not an early revolution by any means; the Zettelkasten method is decades old, but it’s all, deep down, a fancy word for… hypertext. It’s been tried and true at the Internet level.
