A thoughtful comment. Much of the research carried now is a part of immediate future, only in research field. For example, suppose we develop a way to encode information as states of electron spin. This opens a huge avenues for quantum computing, although only at the level of labs. To bring out a user product onto a market, that is a whole different story and complicated deal of various factors and fields, independent of research. It makes sense it takes decades or even half a century to roll out considerable paradigm shifts.
