Higher density batteries/energy storage. I so want to make a coilgun that beats a rifle, but doubt even vehicle mounting would overcome the staggering amount of energy needed. On that note, why not room temperature superconductors too? Then the wires could be thinner and we could have quantum computers outside laboratories as well

Safe neural implants. I know they kind of exist but I mean the one that can make us super smart or help change our bodies. For example it could help regulate hunger for weight loss.
