I would argue the term "gatekeeping" is being twisted around when it comes to AI. I see genuine gatekeeping when people with a certain skill or qualification try to discourage newcomers by making their field seem mysterious and only able to be done by super special people, and intimidating or making fun of newbies who come along and ask naive questions.

"Gatekeeping" is NOT when you require someone to be willing learn a skill in order to join a community of people with that skill.

And in fact, saying "you are too stupid to learn that on your own, use an AI instead" is kind of gatekeeping on its own, because it implicitly creates a shrinking elite who actually have the knowledge (that is fed to the AI so it can be regurgitated for everyone else), shutting out the majority who are stuck in the "LLM slum".

Making ham radio operators learn Morse Code was "requiring someone to be willing to learn a skill". Also pure gatekeeping.
