the context of GUI use has also changed dramatically.. UIs were used to manipulate semi complex to complex formal documents in 2D, people were trained, it was all very important .. nowadays we can bring it down to swipe and tap over floating selfies. I'm sure nobody in the mainstream would ever use an 80s application no matter how good/better it is.
true but i have a feeling that for the next years to come, good old 2d static abstractions will be out of the picture (replaced by fully fluid animated UI paradigms)
