A potential room-temperature superconductor, and something Gen Z will milk the heck out of. If enough time is allocated to LK-99's research and development, it would be the biggest inventions of the 21st century, and something that the general public will hear at least once.

This was originally published by three South Korean researchers just casually experimenting in their university/whatever lab they were working in. The research paper is not peer-reviewed, and was published to a archive research site.

We will finally be able to have super fast friction-less trains and hover-boards from Back From the Future movies. If you don't don't hear it at all in the coming 30 days, maybe it turned out to be another flop.
Some 3 guys in Korea: we just experimented with a new type of room-temperature superconductor, LK-99, which will revolutionise humanity and the way we use electricity!

Western science papers and scientists worldwide: Uh, we don't think so, unless enough R&D is put into whatever this new substance you're talking about is.

Same 3 guys from Korea: You are free to reproduce our scientific results, if you wish.

The LK-99 Effect 

In July 2023 a copper and lead based supposed room temperature super-conductor, a material that could revolutionize technology, was proposed by a Korean laboratory, and this lead to a scramble of informal publications by authors from that laboratory trying to claim the work and some quitting their jobs. LK-99 was a dud. This process of prominent scientists losing their sh*t over something which most others in their field believe isn't true while the public is riding the hype train is referred to in some circles as "The LK-99 Effect".
The rumor is that Sam Altman was fired from OpenAI because of his believes about a artificial general intelligence. This is a clear example of the LK-99 Effect

Cigarette: Northern slang for a cigarette, used oft by mashed up mancunian ravers becasue of the resemblance of a hot(electric)stove to the end of a lit cigarette. Originated circa 1991 in the early halcyon days of the rave culture; we speculate during a drug fuelled hallucination by said manc.
