person 1: "I don't care man, I'm not voting for Biden unless he intervenes in the Israel-Gaza War"
person 2: "don't you know Biden is 99% hitler? Would you rather have Trump be president?"

Get the 99% Hitlermug. 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

"Ahem."
"...Sorry."
