I think that people are naturally emotional, and anything that we spend a great amount of time with (computers, co-workers, friends) becomes a likely trigger of strong feelings, both good and bad. It may seem weird to have the same emotions about people and inanimate objects, but software falls into a strange gray area between people and objects. It's not alive, yet it requires that we put forth a lot of effort interacting with it.
In "Everything is Miscellaneous" Weinberger talks about searching rather than sorting. Things can be sorted in so many ways that it's much more efficient to avoid choosing just one way of doing it.
Maybe we are still used to sorting because that's the way it has to work with physical items. As people become more used to digitization and infinite copies of things, search will become more and more critical and less likely to be an 'afterthought' in design.
