For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound. For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-) Other things that could happen: 1)…

Not quite related to 2) but if the superconductors research pans out, portable high field desktop sized MRIs would be in the bag. Current portable MRIs are all low field (and to a certain extent, somewhat useless).

So far this material (and pretty much all liquid nitrogen ones) can't be used to create MRI sort of fields. There's a reason they all stick with liquid helium.

I like the idea of this list. Some others: - Quantum supremacy - HIV vaccine - Synthetic life - Discovery of ET life - P vs NP solution

Linux on desktop should be up there. /s

Indoor plumbing in general - municipal sewer systems were a huge change (though not really new technology).

Cold fusion all over again. All the internet predictions of what this will bring are kinda cringey and pathetic

Not even close. Cold fusion was not something we thought was possible under our understanding of physics at the time (Muon-catalyzed fusion isn't what they thought CF was and there are all sorts of things that make it not really something that we expect to ever be particularly useful for power generation, etc., so not much purpose in talking about it)

Meanwhile, all our known physics have no issue with an RTAPS existing.

I hope they're as weak as possible. The worst possible outcome of a room temp superconductor being discovered is stifling innovation to make money off it

Transistors, lithium batteries, leds, etc all enjoyed significant patent protection, but still changed the world. I yearn for a Star Trek utopia as the next, but we do live in a capitalistic world where I hope that someone can enjoy outsized rewards for upending some previously insurmountable physical barriers.

Sure, and millions of people die of preventable diseases in the global south every year because pharmaceutical companies deem it profitable to let them die, and because the global north enforces their patents.

You don't know how it's gonna go. The scientists are going to be fine, they have their careers guaranteed and will receive many prizes for their work.

They don't need a monopoly on a world changing material too.

It would have been more convincing if you had given real past examples rather than speculative future ones :) Although I'm pretty sure there are plenty that many people can think of, so it doesn't really detract much from your point.

COVID 19 vaccine, plus better-than-feared virulence.

The vast majority of science does not take place on Twitter.

All of these are fantasy.

0. LK99 is so obviously a fraud. They've been dicking around with this substance for 24 years.

1. some diseases will be possible to fix, like metabolic problems, but where structures are already formed in an adult organism this will be impossible. Like Autism. Go ahead, change every chromosome in every cell, the malformed brain structures will remain.

2. Sure there will be ignition, but the facilities will be wildly too expensive for commercial power.

3. will never happen with conventional computing hardware. Maybe if someone figures out how to grow actual neurons

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.
