More to the point though: > it's hard to edit or search through what you wrote on paper You'd be surprised how fast queries can be done in the type of physical organization systems that existed before computers! People weren't stupid, they came up with many brilliant systems. There's a great art to organization, summary, and consolidation. Maximum flexibility is usually not synonymous with maximum efficiency. And we've never quite mastered the input system for computers. Editing is generally much better on a computer though, but even that shouldn't be overestimated. As humans we are much more often limited by the speed at which we can think, than by the speed with which we can record that information.
