Long-distance energy transfer without energy loss will make it possible to connect more energy grids and sources together, so stuff like the saharan desert providing solar power to Europe, for example, suddenly becomes feasible. Maglev trains will no longer require lots of power to run, since they could utilize superconductor magnetic levitation. You could make super-efficient processors that wouldn’t really heat up at all. Superconductors are also key to quantum computers, so expect lots of advancements in that field as well. They will also make it much easier to build and run fusion power experiments.

Lots of tech in general would benefit from this discovery, stuff like MRIs, electric vehicles, space telescopes or particle accelerators would become way more efficient, cheaper and easier to produce.

Edit: also, check out this video by Isaac Arthur for some more sci-fi examples of what this tech can be used for in the future (discussed in the second half). It’s more space-colonization-focused and kinda like a thought experiment, but interesting nonetheless.

Reposting my comment from another thread to add a bit of context in case anyone’s curious.

So I read the paper, and here’s a tldr about how their material apparently gains its properties.

It is hypothesized that superconductivity properties emerge from very specific strains induced in the material. Hence why most of the discovered superconductors require either to be cooled down to very low temperatures, or to be under high pressures. Both shrink the material.

What this paper claims is that they have achieved a similar effect chemically by replacing some lead ions with copper ions, which are a bit smaller (87 pm for Cu vs 133 pm for Pb). This shrinks the material by 0.48%, and that added strain induces superconductivity. This is why it apparently works at room temperature — you no longer need high pressures or extreme cold to create the needed deformation.

Can’t really comment on how actually feasible or long-lasting this effect is, but it looks surprisingly promising. At least as a starting point for future experiments. Can’t wait for other labs’ reproduction attempts. If it turns out to be true, this is an extremely important and world-changing discovery.

Fingers crossed :)

No one is going to post news/articles here and then discuss them as they would in a regular post. It won’t get bumped up on the subscribed page if something interesting happens. Most of the comments here are going be about the megathread itself.

So this is effectively banning all the discussion concerning all of his companies. Which might be something you want to do, every community can decide for itself what kind of stuff they want to forbid after all. But I feel like it should be said directly, not via making a catch-all megathread.

Publications like these lower reddit’s future valuations though. I’m not sure whether a two-day uptick in users is worth that. My guess would be that it’s not.

I was curious how current LLMs might handle this with proper instructions, so I asked chatGPT this: “What can you tell me about this Reddit post? Would you write a news article about this? Analyze the trustworthiness of this information:” and pasted the text from the post. Here’s a part of its reply:

This Reddit post appears to be discussing updates in the context of […] Hearthstone and World of Warcraft. However, there are several factual inaccuracies which raises questions about the trustworthiness of the post:

  1. Hearthstone was first released in 2014, not 1994. This error may be a typo or a misunderstanding by the user.
  1. Glorbo does not appear to be a known character in either the Hearthstone or World of Warcraft universe […]
  1. Chen Stormstout is a known character from the Warcraft universe, but the claim about him being the end boss of a new version of Karazhan doesn't match with any known information […]
  1. Dragonflight is not known as a video game developer or associated term in the context of Hearthstone or World of Warcraft […]

Given these points, it seems this post might be either a joke, speculation, or misinformation. […] So I'd recommend taking this information with a grain of caution and verify it from reliable sources.

[…] I would caution against using the information in this post for a news article due to the factual inaccuracies and lack of verifiable sources. Good journalism relies on accuracy, fact-checking, and use of reliable sources. This Reddit post contains several claims that contradict established knowledge, and without further verification from reliable, official sources (like game developers or official news releases), it would not be advisable to use this information in a news article.

So it’s not even an issue with current models, just bad setup. An autoGPT with several fact-checking questions added in can easily filter this stuff.

I know, right? It’s so weird. In every single instance of some bullshit happening it’s easy to brush it off as incompetence or an attempt at profit maximization, but overall it feels a lot like some kind of targeted disassembly of whatever made the internet great and facilitated open discussions.

To save you a click, they used new material combination, thin films of hafnium oxide connected by barium bridges, to create a memory storage device that can encode states in between 0 and 1 to increase possible information density.

Also, the horizon line on their logo looked like a hair on my phone screen and it bugged me the whole time I was reading the article. I accidentally clicked on it trying to swipe it off the first time.

Reposting my comment from another similar thread ‘cause I think it’s kind of important to add.

Ok, so it doesn’t mention wet bulb temperature anywhere, so I went to figure it out. The first thing I was surprised with is apparently most of online calculators don’t take in values higher than 50C.

I couldn’t find the exact data about humidity for that day, but it has been 35-40%+ at a minimum for most days in that region, sometimes even reaching 90%.

So, 52C at around 40% humidity is 37.5C in wet bulb temp. The point of survivability is around 35, and most humans should be able to withstand 37.5 for several hours, but it’s much worse for sick or elderly. 39 is often a death sentence even for healthy humans after just two hours — your body can no longer lose heat and you bake from the inside. That’s like having an unstoppable runaway fever. And with that humidity it’s reached at 54C.

We’re dangerously close to that.

Why imgur though, why not link directly to xkcd?

The concept of emergence blows my mind.

We have this property in our universe where simple things with simple rules can create infinitely complex things and behaviours. A molecule of water can’t be wet, but water can. A single ant can’t really do anything by himself, but a colony with simple pheromone exchange mechanisms can assign jobs, regulate population, create huge anthills with vents, specialty rooms and highways.

Nothing within a cell is "alive", it’s just atoms and molecules, but the cell itself is. One cell cannot experience things, think, love, have hopes and dreams, or want to watch Netflix all day, but a human can.

The fact that lots of tiny useless things governed by really simple rules can create this complexity in this world is breathtakingly beautiful.

Kinda ties into your example :)

A search for Threads content on Twitter currently brings up zero results, despite plenty of links to Meta’s microblogging rival being posted on the platform.
