I got my PhD studying band structure of high-tc superconductors (experimentalist, ARPES). These Cu d-d interactions right at the fermi energy give me huge hope. Feels very familiar to other superconductors (re: all the cuprates). (Note: I specifically worked in a lab that was measuring a lot of the d-wave character / gap-energies of various superconductors) All in all, I'm now much more bullish on LK-99 being real su…

Thanks for your input. What would you need to see to say "I am 100% convinced this is / isn't real"? And how long would you expect it will be before that occurs?

Waiting for Applied Science (the YouTuber) to make some in his lab.

Next is that UFOs are real

Unidentified Flying Objects are absolutely real, though the newer cool kid term is UAP. (From the internet: UAP stands for "unidentified anomalous phenomena." ) It's flying saucers carrying aliens from another planet that's controversial and up for debate.

Which is what "UFO" means to 99% of people.

Just curious, how did you find Covid "exciting"? Making lots of money on the bear market?

Perhaps poorly worded, I meant since before . During Covid I lost a lot of zest for life, felt like I went to sleep in my 20s and woke up an old man.

I identify with that. It didn’t help that around the end of Covid I went through a terrible break up and all my grad school friends finished their degrees and moved while I was still working on mine.

It felt like I went to the bathroom at a party and came back to an empty room and I had to stay and clean up. I knew I’d be done in a year or two, so it felt weird to try and find a new social group when I was on short time, but boy was the end of my PhD a slog in part due to feeling disconnected socially.

This ongoing research saga pretty much the most excited I’ve been about anything since before Covid. It feels like the science equivalent of watching your favorite sports team on an epic rise towards winning a world championship. Even if this turns out to flop, I hope history remembers the original authors favorably. They really did find something that by all accounts could plausibly be a room temp superconductor. An…

Pons & Fleischman was exciting for about 3 days. Some folks kept looking for decades after.

I felt like it lasted much longer. Of course, this was pre Internet days, so I read it in papers and watched on TV

More DFT? Haven't we concluded that has little predictive power?

I’d be interested in seeing a source on that. My understanding was that it was a powerful and popular computational tool. The theory is approximate but approximate theories can still be quite useful if the approximation is a good one.

The most interesting phenomenon revealed so far is that the room-temperature superconductor people and the generative-LLMs-are-God people draw on the same limited global pool of credulity, such that HN cannot be flooded with both ChatGPT worship and superconductor speculation at the same time.

On a related note: I am deeply disappointed by how OpenAI has managed to continually dumb down ChatGPT. I’m sure the shortage of NVIDIA H100s and the demand for their APIs shooting through the roof has something to do with it. Perhaps they’ve switched to a quantized model? Who knows. And yes, LLaMA 2 is awesome. Progress is being made. But it’s slowed down. The novelty’s worn off. Now we’re lacking some fundamental p…

What makes you think we're lacking fundamental plumbing? I am personally still quite convinced it will simply take a bit of time and development to plug in the current AI into sufficient self-testing structures (basically the next versions of AutoGPT) and let it run long enough to map out an entire domain with accurate measurements. Seems more like just a matter of time and a bit of funding - but mostly inevitable and very straightforward. It doesn't even really take GPT4 quality levels to do - that's just a bonus.

https://twitter.com/fablesimulation/status/16813529041528504... These guys seem to be on the leading edge there - making self-referential character-driven narratives where agents talk to each other and build the collective world understanding, all through a South Park Westworld lol

And together, these two phenomena have just sucked all the energy out of the crypto excitation mode.

You think all of the news about crypto fraud might have a chilling effect on the excitation?

lol same as it ever was

The material containing lead is very unfortunate. I have no doubts that (if it indeed turns out to be a superconductor) humans will use it anyway in any context where it provides even a slight benefit (cf. just in the lead department: leaded gasoline, leaded solder, etc.).

the singularity isn't going to implement itself, you know.

The next breakthrough we need is with fusion technology. With unlimited fusion energy, room temperature superconductivity, and (soon) artificial general intelligence, the singularity won't be long off.

What fusion breakthrough is needed that isn't superconductors?
