There's probably other similar chemistries that also super conduct at room temperature. Call it the marching tetrahedra of super conductors.

You are likely correct. Now that this has been shown we will probably get a dozen or more of these over the next decade.

I think the winners will be those which are cheaply and reliably made at scale out of common and non toxic elements and have long durability, or if this isn’t fully achievable something close to this goal.

As if that would have stopped him. He will argue that it’s XK-69, entirely different material and spend decades in litigation trying to bankrupt the inventors or worse.
