> Xanadu concepts are, to a great extent, an alternate (and alien) universe. Many of the ideas, paradigms, and systems pursued by computing pioneers (especially of the 70s and 80s) feel this way, especially those that didn't catch on but are still often talked about. I feel that technological path dependence and an overemphasis on the lowest-common-denominator user (and de-emphasis on power users) has really curtailed a lot of real innovation.
