Hopefully as we pile on more and more examples of different materials exhibiting superconductivity, we can understand it well enough to find a practical high temperature one. Though I think we could go a long way with the liquid nitrogen temp superconductors now on the market. It's still going to be a real chore to design around, but it's got to be a lot easier to deal with liquid N2 than liquid He.
