This does not sound good for those people. Writing is a way of thinking. AI writing assistants are competitive cognitive artifacts. People who use AI to write most of their written communication will get worse at thinking through writing.
You seriously need to look up gatekeeping because that's not what it means at all.
Also you are making stuff up. No one has ever been against learning Latin, it is always being seen as something that a sophisticated gentleman knows, literally the opposite of whatever random nonsense you're claiming right now.
I do agree that there are tasks that are good to offload to AI. I don’t believe that reading and writing should be. AI can be a great tool. Ironically, since you mentioned memorization, I can’t possibly retain 100% the information I’ve learned in career and so using LLMs to point to the correct documentation or to create some boilerplate has greatly improved my productivity.
I’ve used AI as a conversational tool to assist in finding legitimate information to answer search queries (not just accept its output at face value) and generating boilerplate code (and not just using it as another stack overflow and copying and paste the code it gives you without understanding). The challenge is that if we try to replace 100% of the task of communication or research or coding, you eventually lose those skills. And I worry for Jrs who are just building those skills but have totally relied on AI to do the work that’s supposed to teach them those skills.
