As long as there have been computers there has been a very technical way of looking at information. Data is always organized in fixed hierarchies of folders or into tables. This is what slow computers back in the day could handle and which was always easy to program for.

This system worked quite well, likely because it was the only system users knew and it was somehow modelled on the way we organize papers in folders in our office cupboards. However, it is not at all how the human brain manages information.
