I have been doing some thinking and this is game changing but not so much. We won't get hoverboards or flying cars to my knowledge. We will get much cheaper maglev trains, but in America we refuse to build public infrastructure that isn't for cars so that isn't gonna fix it.
We won't get faster traditional computers because those need semi-conductors. There are some patents and theories about superconducting transistors so we may get a "cool running" cpu eventually, but it won't be faster it just won't heat up.
Quantum computers will get cheaper and maybe more available, but they are still a research topic so we are probably decades away from them having practical use (or ever in terms of practical for everyday use, they will break encryption as we know it though).
We will "instantly" save something like 30% of our power generation that is lost to heat, but again that is going to require a massive infrastructure project to replace all high voltage power lines, so that is never going to happen in America.
Brush less motors will be able to be smaller and/or able to take in more energy so they will be more efficient, but we are still beholden to our energy storage density.
There is a theoretical idea of using superconducting rings to let electrons flow around it indefinitely, as an energy storage medium, but I have no idea how close that could be or how dense that would be compared to Lithium Ion batteries, or Fossil fuels which is the real competition.
We will get smaller and cheaper MRI's so medical imaging should get cheaper and more available to the "global south".
Am I missing anything?
