One of my recent blog posts got a comment like that, and I tried to reframe it as "this is poorly written", and took the opportunity to solicit constructive criticism and to reflect on my style. I think my latest post improved, and I'm glad I adjusted my style.
i think some people get excited by the notion of identifying AI content so start doing so without knowing how. truly nothing about your post reads like an LLM generation, it has a very non-LLM 'voice'
Not that you shouldn't self-reflect, but some people's style is going to be similar to the default GPT voice incidentally, and unfortunately for them.
GPT has ruined my enjoyment of using em dashes, for instance.
