Indeed, operating temperature seems to me less of a concern.
Considering how difficult it‘s been to produce LK-99 so far, some skepticism on being able to manufacture the material in mass is warranted, I think.
Still, exciting! I’m hopeful :)
Considering how people are making it at all, within days, with demonstrably poor instructions, seems to suggest manufacturing in mass has massive hope, once some time is given for refining the process.
Also consider just how many people will be working on this with nation-state budgets. It has such general applications that nearly every field tangentially connected to electricity or magnetism would be interested.
It wouldn't be like the investment in something that would be similarly revolutionary but with a less certain end game like fusion.
