YACK

Acronym / Noun
The umpteenth ambitious AI project announced with great fanfare, promising to dethrone the reigning champ, ChatGPT, only to end up in the vast graveyard of "next big things." Often characterized by flashy tech jargon, exuberant founder quotes, and a lifespan shorter than the hype cycle.

"Did you hear about the launch of XYZ AI? They're calling it a real YACK, but let's see how long it lasts before it joins the others in the Silicon Valley shadow realm."
