From what I’ve heard (feel free to add to it or to correct me):

Our technology uses normal conductors. Computers, gaming consoles, smartphones etc are all limited in their performance by the power of the conductors. Super conductors existed already, however they require (near to) freezing temperature. That obviously makes it impossible to use those superconductors in normal daily technology.

If however we could have superconductors who can work at normal temperature and don’t require extreme cold, we could have superconductors that massively increase the efficiency of our technology (more efficient smartphone battery life, better electric cars etc)
