To me this just looks like we're scratching the surface now of technology that will only really be useful to us in the distant future. I'm in no doubt such a superconductive material exists, but whether it can be scaled up both in terms of application and production is an entirely different matter.

The diamond anvil experiments aren't really useful for regular applications. It's nice to know what happens inside planets but if a superconductor requires 1.5 million atmospheres of pressure to operate it's not going to be any use inside my computer. The more promising method seems to me like it will be nanotechnology, the forming of atomic lattices using pure carbon, silver and gold, under very specific geometries, that kind of thing. We're in the very early stages of that technology, this is possibly next century stuff.
