LK-99 is already patented so even if Elon were making a ton of it, he couldn't do much in his products without licensing it from the creators.

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.

The only thing Elon seems to be interested now is embarrassing himself even further

He'd also name another child XLK99.

I put 1k USD into Tesla today with the same reasoning. Hopefully I don't end up a fool!
