You are right, of course, Jones. The point is that application of RTSCs will likely not be something that is a direct extrapolation of how today's superconductors are used. The "killer app" for RTSCs will be something only found when RTSCs materialize, taking advantage of the yet-to-be discovered RTSC unique properties. Part of the problem in finding RTSCs is that they may poorly resemble what are regarded as superconductors today.
