I’m asking where it came from.
I know you can find it if you Google it, but that’s my point: It’s the shibboleth that these people use to signal their alignment with an ideology, and it’s all the same thing.
I could have told you what those articles would have said before I began reading them because “AI booster” is a phrase associated with a very specific worldview. It gets dressed up prose about superiority and condescension for the “boosters” but it’s always the same thing.
It’s like many of the academic phrases that develop to signal alignment with an ideology and separate the insiders from the outsiders.
