One thing that you’ll definitely observe in daily life is the development of fusion reactors. They’re significantly safer than regular nuclear reactors (which run on fission), and also a lot cheaper (theoretically). The current downside to fusion reactors is that up until this point, it usually takes up more energy to run it than the energy that gets produced. So in other words, it doesn’t actually generate enough energy to make it worth building. Most of the energy spent is trying to keep the magnets in the reactor cold enough to function. Since room temperature superconductors should function at room temperature, there will be no need to keep them cold, so a lot of the energy spent keeping the magnets cold will become unnecessary. This will significantly improve the development of fusion reactors, to the point where it is possible that we may even see fusion reactors on our energy grid in our lifetimes. Basically, if this claim is true, you can expect that energy costs will become virtually negligible and the world will almost completely run on renewable energy
