There was a point where it was pretty simple not to use the internet, too. This analogy drives a question: were those people who rejected the internet at the beginning better off in the long run, when compared to people who embraced it?
Generative AI can be a very useful productivity tool. Choosing not to use an available tool is "easy", but is it wise?
I find myself agreeing with the person you responded to; you don't appear to be thinking critically about the implications of LLMs/generative AI. That, or you are speaking more literally than it seems, and you mean, literally, that it's easy not to use AI, without commenting on how wise that decision may or may not be.
