Get the 99 Stepsmug. 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

Get the The LK-99 Effectmug. This frequently used term was coined by J.A, simply meaning someone who is one of a kind. While it’s unrealistic that anyone could be perfect(100), a 99 is indeed intriguing and unique. They stand out from the herd and could quite possibly be wifey material. Usable for the most unique of women and men alike regardless of appearance, a 99’s soul just speaks to you.
I think this girl might be the one she makes me feel like no ever has, she’s so different from everyone else it’s so refreshing she’s A 99.
