Exactly, the 99 stands for 1999, so potentially this material has existed for over 20 years and we could have started testing and replication on a much wider scale a decade ago. What benefit have we gained by disseminating this research so slowly?

> What benefit have we gained by disseminating this research so slowly? It's less visible, but at this scale there's a high cost in everyone pausing their research to replicate LK-99. If it turns out to be real that's worth, but if not it could've gone to better use. Think of what we could've done with the time we spent reproducing cold fusion. It's survivorship bias; yes, you would love to see the significant discov…

Seems extremely unlikely there's a "high cost" because it's already clear there's some strange properties involved in LK99. Cracking the explanation for this could potentially help advance material science in all sorts of ways.

In some ways this is pure science. Multiple groups working on the same thing increases the chance of searching the problem space thoroughly, and not missing out on finding better local maximas.

Seems to be the same one that had a video a couple of days ago https://news.ycombinator.com/item?id=36953396 Back then, many asked if this was superconduction or merely diamagnetism. Does the new paper shine any light on this question?

Yes, in two forms: First it shows a temperature graph vs moment, as they heat it it loses the diamagnetism around the temperature LK99 is said to be superconducting. Second only a superconductor will have net-zero field, which means "stable" levitation. In the video they approach the sample with the magnet and flip it while the piece is mostly "in place". A regular diamagnet generates a external field that "follows"…

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.

Disposable razor? What's that doing there?

Unless it's too comment on 'throwaway mentality', modern consumerism, etc., the book meaning 'made the modern economy' more literally/broadly than you're referencing it for here?

Here is a good thread on what could be realized if we had room temperature superconducting materials at our hands: https://twitter.com/alexkaplan0/status/1684044616528453633

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)…

I think every technology is double edged, from the humble hammer all the way to atomic energy, you can always apply tools for good and for bad.

double edged hammer is certainly a useful tool but I prefer the one with the thing on the back for nails

What happened, for those who want to catch up: https://twitter.com/8teAPi/status/1685294623449874432 With the anti-hype hype that surrounds this discovery this was to be expected. Why would I disclose this kind of research to the public so that the whole world can benefit from it when I'm called a fraudster or a liar. Why would I risk my reputation – no matter how I spin my research – in a sacrificial circle jerk whe…

that account is fan fiction

Yes a real grifter at that as well.

Makes operations way more sanitary. Many people used to die post operation due to infections.

Sorry to piss on your sunny parade, but: >> 1) Fully decoding the cellular mechanism of cells allowing for the curing of any disease, repairing any genetic disorder. -- so you want to cure aging then- how many billions of people you think can a planet with a 6k km radius sustain ?

Doesn't seem that it would cure high speed lead poisoning. People will continue killing each other just as well.

If you experience dystopian events, you cease to be, preventing information pass on. All instincts and warning signals, by there very nature are accurate, until they can not be any more. How do you build a warning system for a unsurvivable event, with not wittnesses? Eternal unease and anxiety, regardless of reality.

I think you're mixing up dystopian with apocalyptic.

webster's dystopia definition is "of, relating to, or being an imagined world or society in which people lead dehumanized, fearful lives : relating to or characteristic of a dystopia"
