Update from 2 hours ago https://twitter.com/floates0x/status/1687296154416066560

"LK-99 Updates around the Korean Verification Committee:

- Sample will not be released today/tomorrow

- Group waiting on peer review (implied to be APL materials) and could take 2-4 weeks

- Sample possibly with APL Materials, which is why it cannot be provided to verification committee

- Team is asking the Verification committee for a detailed plan on how the committee intends to perform the verification before proceeding

Now, Hyun-Tak Kim also issued the following quote in regards to the Korean Verification Committee: '돈을 빌려서 어렵게 사업하는 분들한테 와서 조직적으로 횡포를 부리는 것은 바람직하지 못하다"며 이같이 밝혔다'."

Can anyone translate the Korean?

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)…

1. Anti-gravity

2. Light year capable transport

3. Inertia dampers

4. Mass scale carbon capture technology

5. Robots to prepare space for habitation

6. World recognition to manage resources globally

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.

Nuclear weapons. There hasn’t been a full scale war between major powers since.

There's been plenty of war, and it could well be the first step on a path to the end of life on earth. I imagine this belief stems from all the "Hiroshima and Nagasaki were necessary/good" propaganda.

What you're missing is the fact that in today's world, where almost every aspect of life is subject to top-down control, any "enabling" technology above all else enables oppressors to oppress more effectively.

If free-form gene editing were developed today, you would see the elites using it to make themselves immortal, while denying the same to everyone else. If fusion power suddenly became viable, you would see the richest people using it to make themselves even richer, while cementing their stranglehold on vital infrastructure. And it should be obvious to anyone who has been paying attention during the past 3 years that artificial intelligence is above all else an instrument of control, and even in its infancy, access to it is unevenly distributed along the same strata of power that already existed before.

At this point, the only "black swan, but good" event that could happen is a cataclysmic reset of civilization that might somehow see a better phoenix rise from the ashes. Barring that, we're full steam ahead to a techno-totalitarian nightmare future.

What temperature?

326K (+127 deg F) and 340K (+152 deg F) for their less and more pure samples respectively. And, yes, if it's a superconductor as we understand them, that's the temperature at which it would have zero resistance as well.

53°C and 67°C.

Wow.

> Why are't more labs outside China making LK-99 and publish videos? Good rigorous science takes time to produce. It can take anywhere between several months to a year or more, and the career implications for rushing something out that is later found lacking is not great.

> the career implications for rushing something out that is later found lacking is not great. On a tangent, this idea of reputation keeps on coming up in this whole discussion and I am burdened by it in a way I don't fully understand. The way people have talked, if this LK-99 doesn't work out, then it is almost as if those who published this did something _morally_ wrong. Well, morally wrong is not quite true, but th…

This is an good point. I think there is a difficult balance to strike between open communication and adding confusing noise to the scientific literature. Partly for historical reasons, there is an expectation that published science is correct to the best knowledge of the authors. Since writing, publishing, and reading papers takes a lot of time and effort, there are advantages to this precedent. I work in physics, and I can tell you that if we published all of our half-baked and often wrong ideas, we would waste a lot of people's time, at worst sending people down blind allies that we would soon rule our ourselves. I suppose tying reputation damage to publishing incorrect or misleading results is then part of the incentive structure that keeps publication quality high. At the extreme, there's was one recent LK-99 paper that had an obvious glitch in their data, and instead of taking a bit more time to debug it, they just posted the paper and speculated about what was going on. If that's how much you're rushing, how do I know I can trust your data?

But there are costs to this. There are big gaps between what people discuss with colleagues and what gets published, and the is no forum to publish partial or negative results, except maybe conferences. Ideally published papers stay at a very high bar, but there are other forums to publicly share work in progress. In a way Twitter is becoming this.

Penicillin has gotta be on that list. Just randomly happened to culture on a Petri dish left out on vacation, happened to be the worlds first antibiotic

I can't imagine what it must have been like for people to hear about yet another "miracle drug" that cures most diseases – and then gradually realize that this one actually works.

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.

I was interested in learning more, based on your comment. Here's what I found out.

City of Hope thinks they've found a chemotherapy that's "able to kill all solid tumors","in more than 70 cancer cell lines".[0]

According to the National Cancer Institute[1], there are "more than 100 kinds of cancer". They're listed here: [2] Some of those cancers are soft tissue, so they aren't affected by this treatment.

I didn't know what a cancer "line" was, so I looked it up. "Cancer cell lines are valuable in vitro model systems that are widely used in cancer research and drug discovery."[3] So, they're not cancers in people, but cell cultures they can test drugs on.

This probably doesn't give you much more information than you already have, based on what you heard elsewhere, but I learned enough to figure maybe it would help someone else, too.

Whether this'll work in people, I guess we'll find out when they start the Phase 1 clinical trial. If you, or someone you know think you might benefit from this, there is a link to sign up for Phase 1 trials.[0]

It appears to have worked in pre-clinical trials, so they have tested this to make sure it doesn't kill people outright, the same way it does cancer cells.[4]

Democracy is a diversion technique honestly. “Rulers” are always a few people/corps and the fate of the people depends on them.

The key is being able to throw the bums out every 4-8 years. This gives Democracy a self-correcting feature that doesn't work with lifetime rulers.

I'm unsure if we want people living forever. While disease, illness, and senility are terrible things, as soon as people can live forever we will have eternal dictatorships (or people trying for it) as well as other questions of perpetual inequality. "Death renders all equal".

Also there’s a massive philosophical quandary in there too.

If people could live for much longer then they’re likely disincentivised to procreate due to worries of overpopulation and then, in one way of thinking, you’re hypothetically depriving a line of offspring of lifetimes they’d otherwise have if you’d had what we consider a normal lifespan now.

Yes I realise there are probably an infinite number of takes on this, I’m just pointing out one possible way of looking at it for the sake of saying not all technological advances have universally positive outcomes.
