Everyone is so excited, and it is exciting, but I guess I don't see how this will "change the world". It doesn't seem applicable for transmission lines (it's brittle and cannot conduct large amounts of current), which is what I would imagine would be the biggest world changing thing. Maybe it could make maglev trains a more common reality? But we seem to have trouble building trains of any sort. If you could use the material for PCB traces you could eliminate (a lot?) of heat loss from computing equipment. But you're still stuck with Si on the chip itself. You're still stuck with high voltage copper power lines.
What, exactly, are the "world changing" applications? Perhaps my imagination isn't up to the task of seeing this. What I see is a novelty for physics students to levitate magnets without the need for liquid nitrogen, and perhaps it will make some quantum computing designs more efficient (and therefore render PKI obsolete. yay?)
