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)…

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.

Thousands of breakthroughs had to happen for you to be able to post your comment.

I'd go as to far as saying GPT-4 is capable of fairly complex reasoning, at least in my experience tossing complicated questions and situations at ChatGPT Plus.

GPT4 is simultaneously smarter than and stupider than anyone you've ever met.

I think that's a hilarious and accurate way of describing it :-)

1) Subset breakthrough here potentially related to cancer, we'll see how the peer review and evolution to becoming an available standard of care goes. City of Hope scientists develop targeted chemotherapy able to kill all solid tumors in preclinical research https://www.eurekalert.org/news-releases/997141

I've heard elsewhere that "all solid tumors" should really more accurately be conveyed as "all solid tumors with a very specific mutation". It is, apparently, a very common mutation, but also not universal, even among solid tumors.

Apparently. I'm not an expect, but it's what I have encountered elsewhere.

Still great news! But not quite as revolutionary as the headline implies.

On a completely different front, let's say the paper completely checks out and they have discovered this miracle. How strong are the patent protections on materials science? For example, if someone could replicate the effect with lead + gold, would that be considered a novel material which would not be subject to licensing? Is it the material itself or the method of production?

> let's say the paper completely checks out and they have discovered this miracle. How strong are the patent protections on materials science? If it's literally a room-temperature superconductor, the present state of the law is irrelevant. China won't play by the rules. If Korea tries to corner it in the West, the rules will be replaced. (This would have been true had the inventor been French or American, too.)

Completely my train of thoughts. And it is not only china. Patents are based on laws and laws serve a society... If that does not work anymore (obviously after a long and broken process) the law changes.

Green Revolution; most people have never heard of Norman Borlaug, despite being responsible for saving hundreds of millions of lives.

I get the idea of superconductivity at room temperature in theory. But I don't have enough knowledge to understand in real terms, how will the world change if this is true?

It means we won't lose MRIs when the earth finally runs out of helium as they require liquid helium to run the superconductors that generate the magnetic field. We're running out of helium with no way to replenish it. Helium is the only element on the periodic table which is a non-renewable resource on Earth. So MRIs will get much cheaper, and they could end up being as cheap as taking an x-ray today.

Based on our current data LK99 isn't a replacement for helium cooled superconductors for the same reason YBCO and similar aren't - critical current/critical magnetic field aren't in the right ranges for what we need out of MRI machines.

I do think it's too early to say one way or the other what all of this ends up looking like, so we might find that purer/larger samples have better properties than what was measured so far, or the discovery puts us on the trail of other RTAPS in the same class that might be better for these purposes.

I'm looking forward to experiments with LK-99 and twistronics. What a time to be alive. https://en.wikipedia.org/wiki/Twistronics . https://arxiv.org/ftp/arxiv/papers/2101/2101.04501.pdf

I think LK99 is a 1D — not 2D — material.

1) doesn't make a whole lot of sense. A perfect understanding of something doesn't mean you can fix anything wrong with it. 3) has already happened. The AI chat bots aren't very smart, but they're clearly capable of some degree of basic reasoning.

Not sure that AI chat bots are actually reasoning in any basic way, so much as they are filtering out noise and presenting an output that might satisfy the input, but it's often quite wrong. It's still more of a parlor trick than it is intelligence or reason.

> Not sure that AI chat bots are actually reasoning in any basic way, so much as they are filtering out noise and presenting an output that might satisfy the input

Not sure if there is a difference, for sufficiently abstract interpretations of “satisfy the input”

China is taking the lead, they harvest the fruit of their massive investment in education 20 years ago, congrats!

This is a South Korean breakthrough

I am not stupid, I know that

However, take a look at this: https://en.wikipedia.org/wiki/LK-99#Replication_attempts

0 from both the EU and the US

Getting downvoted over this speaks volume ;)
