> What parts of note-taking should we digitize? What aspects should remain firmly in human hands? And most importantly, how do I create a tool that enhances rather than replaces human thought?

My personal philosophy is to use the most primitive methods possible and only use technology when there really is a strong need to go to the next level. It exposes what I really need, what are the weaknesses, etc. For example, I take all my notes with pen and paper. But if I find that I'm really referring back to something, I might write it up in a document. I don't see the point in digitizing everything right away if I'm never going to use what I write.

Moreover, writing things first by hand helps me remember them better and "feel" the knowledge through my hands.

Same thing with photography. I don't tend to use the burst mode on my camera unless I REALLY need it. When it comes to accomplishing things, I found (personally) that asceticism with tools is best.
