After reading this comment thread, I got curious and went through his history. While I agree the prose reeks of LLM tells, the messaging seems a little too nuanced and correct for 100% LLM use. Also, he's directly confirmed using the LLM to write clearly as English is not a primary language.
@miwa, thank you for taking the time to look into my history. It is encouraging to hear that you felt the "nuance" in my words, as I struggle a lot to balance my thoughts with the limitations of translation tools. Your comment gives me the confidence to keep trying.
