I’m hoping something like LK-99 is confirmed 
It could allow orders of magnitude faster CPUs in the future, and suddenly Crystal compilation times would not be an issue for big projects.

That’s not a video from original paper authors :)
As for attempts in different labs it’s probably too early to tell, as the results seem to differ which could be due to different labs getting different substances (maybe LK-99 is hard to synthesize?).
I’ll stay optimistic and wait for easily digestible answer like Sabine Hossenfelder promised update on LK-99 here https://www.youtube.com/watch?v=LoKWourNJEs
Superconducting computing is already a thing. the current clock rate is only 2.5Ghz but they are expecting that it can reach 10Ghz… then again it needs liquid nitrogen cooling, with that setup you can do overclocking yourself.
I think as crystal users we should explore the idea of using a dedicated dev machine that will be as powerful as possible, then you can just use VS Code remote connection (or similar functionality for other editors) to connect to that single machine. I do it with my laptop/desktop pair and am pretty happy with the result. Even when I were away from home the developing experience is still the same.
No need for extreme cooling for room temperature superconductor. LK-99 is claimed to have zero resistance at temperatures up to 400 K (127 °C; 260 °F).
Completely replacing current tech based on semiconductors by superconductors could mean 100x faster computers (A world-first one-way superconductor could make computers 400 times faster)
I know. I want to believe too. The recent weeks I have been following that topic very closely. But the chance it is real is really slim. And even if it is real, there will be many technical challenge before it can be practical, like 20 more years minimal (the situation with YBCO).
We can’t wait that long.
LK-99 isn’t a superconductor — how science sleuths solved the mystery
Replications pieced together the puzzle of why the material displayed superconducting-like behaviours.

That’s a poorly written article in the opinion section. Pretty much worthless.
Me too! even, i am keeping finding the change of investing for it, i will very sad to know LK-99 is not a superconductor, i still consider LK-99 is useful, even if it’s not what it claims to be.
A good candidate for superconductors is fullerenes. However, these molecules are quite expensive. But there is a more affordable and interesting option - shungite, because there are fullerene molecules in shungite carbon.

By the way, shungite is an excellent conductor at room temperature. Perhaps, under some special conditions in the future, it will be possible to use it and detect superconductivity at room temperature. In the meantime, it becomes a superconductor precisely when the temperature rises, which may be and will be better.
Unfortunately, multiple replication efforts[1][2][3][4][5] concluded that LK-99 likely doesn’t have any of the properties that make a superconductor
