Problem of medical notes have a name: bureaucracy. The hope is leaving it apart, and today it seems a bit utopia...

Also in terms of "numeric/digital" vs "paper" the point is ignorance: how many people outside IT world (and even inside) do actually know enough a desktop to take their own personal notes in an ordered, usable and useful thing?

IMVHO a so small percentage that we can probably know them all by name. Just take a look at a "common" mailbox: most of them are an utter pile of data, few with some incoherent taxonomies, few even with the sole inbox as an archival place. Than take a look a common "home directories": the very same mess. And if this is for personal and generic data do you think that those people are able to properly not only manage but share helpful information with digital systems?!
