It's so hard not to be crazy excited about the future. The past few months are proving to be an absolute breakout for the literal human race. So far we've seen: 1. in Dec 2022 We saw a fusion breakthrough seeing a net gain in energy 2. In March GPT-4 was released, which seems to be a seminal breakthrough in AI, and maybe of our first glimpse in what could become an AGI. 3. In May we find out apparently our government…

Regarding #1, it pains me to see so much hype about this feat. To restate it. We were able to simulate the implosion of the secondary stage of a thermonuclear device in a lab by the means of lasers, to the point that this simulation has ~ 0.001% the efficiency of a real device. We also probably learned a lot about the amplification of x-rays by the casing material that would have been useful during the SDI days of th…

Beyond a certain point, every energy system is a weapon first. Uncontrolled precedes controlled.

Several commenters here have mentioned demonstration videos. Does anyone have a link(s) to these? Many thanks.

Try the sources column in this[0] table. You can expand the notes for each entry to read more. There's also this one[1] that's on the front page right now, though its provenance is questionable.

Thank you for the reply. This is helpful.

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 t…

I can relate to both comments. Covid really sapped the life out of me. Some relationships broke down during isolation, I lost friends, my fiancée left, I felt stuck in a job that I hated... The research into LLMs and diffusion models started to wake me up, but this superconductor research has, for some reason, really awoken something in me. I feel excited about the future– my future! – for the first time in a while.…

That’s a tough run. Even if it’s a silly reason, any excuse to be whimsically excited about life is a good one.

This could also explain why the original authors themselves say they can only make it successfully around 1/10 times. The stars need to align.

That’s not unsurprising when it comes to a lot of research. The bench scientists I know often struggle with yield rates and labs have special knowledge about their particular set up when it comes to getting stuff to work. Even in robotics (my area), if you are watching a video of a robot doing something cool, there’s often a bunch of times they ran the same demo and it didn’t work for some (often largely irrelevant t…

Hail real-world, the destroyer of theory-nerd arrogance.

The least interesting phenomenon revealed so far is that HN is split into a group who are entertained by watching and discussing emerging tech / science news, and a second group who are entertained by disparaging the first. I enjoy watching floating rocks and talking to computers.

I would say I am in both worlds. Not too excited about a lot developments in computer tech, but mostly because there is a lot of hype on technology that tends be impressive BUT misses the mark on the bold claims. But with this LK99 stuff, there is not much room for vague wiggle room. The requirements are very clearly defined and if they do it. It is done! It isn't a case of "if in 5 years and $X billion we may be abl…

Exact opposite for me - with stuff like AI tech, I'm a lot more familiar with the subject matter than the happenings in the material sciences, so it allows me to be more confidently optimistic about computer-related advancements. Even if my education is still insufficient to grasp the full extent of new tech, I can at least try to understand it conceptually.

On the other hand, the LK-99 news seem very promising, but a lot of professionals in the field are still iffy, and everyone who's interested in emerging tech is left searching for breadcrumbs and talking to other enthusiasts. It's likely that we won't know if this is a dud or a world-changing discovery for several weeks to months...

I've been trying to be as cautious as possible when looking at the recent news, but it's difficult to not be cautiously optimistic about at least some things.

I’ve seen several tweets implying the gubberment is rushing out RTAPS to “cover up” the alien stuff

What is RTAPS? I tried searching but got a bunch of conflicting acronyms!

Maybe some related to a NASA project?

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.

The biggest threat to Bitcoin wasn’t apt criticism. It was a nexter bigger thing.

Bitcoin was really 'done' 10 years ago. It does what it does and there really isn't much more to it. People tried to keep the hype going with DAO's, earn programs, smart contracts, NFT's, etc.. but crypto was already done before 'web3' even started.

2023 will go down as a miracle year not unlike 1905. Between AI, this, and… what’s next?

I'm missing a lot of historical context, so - what exactly happened in 1905? Was there a myriad of major scientific discoveries?
