  • Risk assessment is probability and severity. The probability can be vanishingly low, but if the severity is astoundingly high then acting like a high risk situation could be appropriate.

    Take asteroids. The last planet killer to hit us was 94million years ago. A rudimentary estimate could put the probably as 1:94mil. The severity of an asteroid impact of that magnitude is off the charts, so it is reasonable to consider it a risk and act accordingly to spend resources to search for and track asteroid trajectories.

    The severity of abduction, murder, and rape is probably pretty high for most people, so considering it a risk even with a very small probability is not unreasonable.















  • Semiconductors are used for transistors because they give us the ability to electrically control whether they conduct or resist electrical current. I don’t know what mechanism you’d use to do that with superconductors. I agree you don’t ‘have’ to have resistance in order to achieve this functionality, but at this time semiconductors or mechanical relays are the only ways we have to do that. My focus is not in semiconductor / IC design either so I may by way off base, but I don’t know of a mechanism that would allow superconductors to function as transistors (or “electrically controlled electrical connections”), but I really hope I’m wrong!
