Everyone with half a brain in the US is working the ad-tech and data-mining industries, that's where the money is.
I suppose the researchers at Lawrence National Lab in Berkeley, whose analysis and pre-print replication effort is cited in the linked article, are working with, what, quarter-brains?

Resistance is what makes things hot, and heat is what makes dumping huge amounts of charge current into batteries a bad idea. No resistance → no heat → no need to charge with low current†. Another way to say it is that, with a superconducting wire, you can make the wire as thin as you want and still pass the same amount of current through it, without melting the wire. Picture using a USB-C cable to charge your car. †…

How about LK-99 coins!?!? Right? Maybe we use diffusion to design them so they are "super-conducting crypto AI coins" get yours now for only $199 at the Philadelphia Mint. Act now, supplies are limited!
I'm going to use my new skills as a Prompt Engineer to get Stable Diffusion to produce some NFTs for me, and use the profits to invest in a SPAC targeting LK-99 start-ups. Now explain that sentence to a caveman - or even to someone in 1990.
The ramifications of the inflection point we are currently at is mind boggling. I had a hard time explaining this last night but we may very well be witnessing the beginnings of a technological transformation era much like when the p-n junction was invented. From the 1940s standpoint it would be hard to envision all we had today. - Lossless transport of energy - Batteries that don't take any time to recharge - Faster…

There are limits how much you can pump into it, it isn’t magic… but it almost is actually.

I'm astounded that the MSM seems to be ignoring this ATM. I did a Google news search on LK-99 and saw nothing from major publications. A search on the NYTimes returned an article from 1974.
Most people I talk to don't recognize the importance of room temperature superconductivity. A floating grain is cool, but not something that jumps out at people like a rocket or a big fusion reactor. The application is similarly unintuitive. Many here on HN ask why such a thing would be important, and they are probably the 99th (or 99.9th?) percentile in materials science and EE literacy.
I don't. I read someone saying it would be the biggest breakthrough since fire. Is that true or hyperbole?

Watch gold be the only practically viable solution, making this new material wonderful but also incredibly expensive.
Time to start mining asteroids.

> They also predict that substituting gold atoms into the Pb(1) site could lead to a material with very similar properties, which will be an extremely interesting idea to put to the test. Since the base material is lead apatite, I had a random thought that maybe medieval alchemists trying to turn lead into gold just had it backward, as doping gold into lead might be a breakthrough. :-)
I want to believe. After several millennia of killing people for gold, we can finally put all that gold to good use—using it to create superconductors that can power energy weapons we can use to kill each other. ♫ It's the circle of life ♫
