Some of us just write that. AIs had to learn it from somewhere.
I don't think that commenting on every article is going to make the posters suddenly decide to go back and rewrite it by hand. Some of them probably don't even speak English natively. The comments are getting more tiresome than the AI prose at this point.
Hopefully in a year or so the LLM output won't be so janky and obvious, so this might just be a phase everyone has to pull through.
I can write competently, but it's natural direction is towards emotional rhythmic flow that can convey emotion/passion...but which for scientific writing, can get in the way of clear clean communication. So, I write what I mean,and Claude straightens it out...and these days (i.e. not last year), it doesn't lose my meaning that often. And since I wrote it first, these AI-isms appear less frequently, and if they do, I revise them away.
