You're right because writing is like everything else in life, you have to focus on controlling what you can control yourself, not controlling what others do. It takes focus of yourself and enjoying writing if you are stressed or angry about AI etc. As you said there are mechanisms in place for limiting AI written through algorithms, and better to just focus on your own writing. Those obsessed with others are just like in ordinary life, where they try to control what everyone else does, instead of controlling themselves. As you have yourself discovered feeling stressed and angry is no way to write and it takes value from your writing. People getting heated and annoyed about AI are doing themselves a injustice and devaluing their own writing. I like your story, it’s reasonable and well balanced with different views, etc, and great self understanding. You have the ability to see the human/AI situation from different angles, which opens discussion, not negative reactions.
