What an odd name to me, becaus "Vibe" is, in my mind, equal to somewhat poor quality. Like "Vibe Coding". But that's probably just some bias from my side.
Vibe coding just became a term this spring.
I doubt that that the substantial part, like giving it a project code name and getting company approval of this research project started after that. It's not libe vibe has a negative connotation in general yet.
