People called the Soviet anime lesbian kitchen chemist a LARP but this is either Nobel or a fraud, personally very heavily leaning towards fraud.

> batteries charge instantly Correct me if I'm wrong, but wouldn't there still be a bottleneck on the battery chemistry itself?

The Superconductor would also store the Energy. It could instantly release and take in energy. So this would also be the battery

> It could instantly release and take in energy.

In that case, can it be used to create new type of explosives?

> 6. World recognition to manage resources globally Do you mean communism?

I don't care what it is if it means we destroy fossil fuel production.

1) doesn't make a whole lot of sense. A perfect understanding of something doesn't mean you can fix anything wrong with it. 3) has already happened. The AI chat bots aren't very smart, but they're clearly capable of some degree of basic reasoning.

I'd go as to far as saying GPT-4 is capable of fairly complex reasoning, at least in my experience tossing complicated questions and situations at ChatGPT Plus.

Chat-GPT is not capable of any reasoning, let alone “fairly complex”.

To be clear, they are not sorting it by superconductivity. Their claim is that they are sorting it by the Meissner effect. More likely they are sorting it by it's exhibited diamagnetism.

Assuming this is indeed the holy grail of superconductivity... can someone with knowledge on manufacturability of these materials, suggest a prediction of when the specific LK-99 material would be ready for mass production? Is it ~3 years from now or more like ~15 years from now?

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?

As referenced by GP - it's a list of inventions from the podcast '50 Things That Made the Modern Economy.' [0]

The first series is my favorite podcast of all time. They're short (~8 minutes, iirc) but pack a lot of interesting info in each episode. In particular, they explore some of the second-order effects of each invention.

The disposable razor might not be a true 'black swan' like the transistor or LK-99, but some of the background and influence around the invention might surprise you! I recommend checking it out. [1]

The last week reminds me of the story of Bardeen & Brattain's invention of the transistor (e.g. in The Idea Factory ). It barely worked and heaven forbid you bump the table. There was even a third slighted figure who wanted credit. Part of me wants to be skeptical but OTOH if it's hard to reproduce that seems totally normal. How exciting that some other people have got it working now.

Things also tend to be invented at about the same time at different places. I wonder if there are other people who were this close to invent it but just couldn't get it right.

Last year I read The Double Helix and The Code Breaker within a few months of each other, and what really stood out to me is that while we celebrate the first person who discovers something, in reality there were several teams all racing to the finish line, and were sometimes days or only even hours behind in presenting their findings. Yet only one team gets the accolades and their names in textbooks, the others are a mere footnote at best.

This was my first time reading about the history of discoveries like this, and I guess prior I thought these celebrated names had moved humanity forward by decades if not centuries by connecting the dots of the runes of the universe, but the reality is really very different.
