Room temperature superconductors would represent the greatest leap forward since electricity itself. Ultra-cheap, ultra-high resolution MRIs, lossless power transmission across vast distances, massive gains in computing power, much lower cost supercolliders for advanced physics, low-cost magnetic confinement for fusion power experiments, and so on.
No money for salaries, the private jet lease and corporate penthouse really dig into our profits. Work harder and maybe we can afford a bigger jet!
