I enjoyed the idea of "wantum physics" and think we could usefully have "wantum computing".
By "wantum computing" I don't mean quite the same as "wantum physics". Wantum physics is fictitious science made up by a science fiction author, to do what is wanted to further the plot. "Lithium crystals", "flux capacitors" and "midichlorians" spring to mind. By wantum computing, I mean computer technologies that are in that tricky gap when the potential benefits have become clear enough for organizations to "want 'em", but there's still a substantial risk that the benefits can't actually be delivered. So a project is tried and overruns badly or has to be abandoned. Or (perhaps more sadly) the project is completed and released to baffled or indifferent users who don't think they have a problem for that solution.
It's usually a matter of jumping too early ("making a wantum leap" I suppose). "All of this has happened before and it will all happen again." In the 1990s, many publishers invested in CD-ROM publishing, expecting a move to electronic formats from print. That shift is even now under way (it has gone a long way if you are a scholarly journals publisher, nowhere near as far if you are a fiction publisher now moving into eBooks). Then there was the dot.com boom just before the millenium- massive investment on the promise of a big shift to online eCommerce and marketing. Well that did happen, arguably is not complete yet, but took longer than the enthusiasts thought.
CD-ROMS, dot.coms, "Web 2.0", Cloud computing... in each case there were (or are) early success stories, to enthuse and frustrate those who made the wantum leap a bit too early: for whatever reason they didn't turn out have the right combination of factors to break new ground successfully.
