The only way people will get to self-expression that's worth hearing is by working their way through the self-expression that wasn't.
In a better world that would happen in school and as a normal part of growing up, but at least in the US, that mostly doesn't happen.
If humans use LLMs to write, it's much more likely they will never uncover the unique perspectives they could share with the world.
So, for those whose parents and teachers failed them, embracing, encouraging, and engaging their clumsy, self-centered rudeness is, I think, the best path forward.
Granted, when it is clumsy, self-centered, and rude, one of the more helpful things we can do is offer the critiques that clearly and coherently point that out, as you've done here.
...though I stand by my claim that using LLMs to write is actually deeply offensive and rude, a rejection of what it means to be human, and that it should be met with strong rejections.
