This. My small brother tried to explain to me, an electrical engineer, why this will change the world.

I then had to give him a rundown of things that would need to happen before there ever could be a widespread adoption of the material in common household wiring. First it needs to replicate, then a lot of research has to happen on the properties, then manufacturing processes have to be explored and created, suitable insulator materials have to be found, the price point of the sold wire has to be low enough, ...

Hope for a better future is a good thing, but WHY does it always have to come in the form of technological silver bullets these days? Because then we don't have to change our way of living?

Don't get me wrong, a room temperature, ambient pressure superconductor would be revolutionary and (provided it can be manufactured and used without a ton of hassle) it would transform the world. But it would still probably take two decades and there are so many other fronts on which we as a humanity have failed.

"But it would still probably take two decades"

Two decades is a lot of time. Transistors or airplanes got to a useful form much faster, in a less wealthy world with many fewer engineers.
