No LLM has responded like your quote of OP that you assert is LLM generated. Dense verbose writing is not something LLMs do without very specific prompt engineering that no one would do rationally. The tropes of LLM writing are more highly sporadic verbose writing (e.g. "delve") with highly atypical grammatical constructions, it's more precise than "it's sounds like a MBA" like you are asserting. Look at Wikipedia's list and try to figure out which item the OP falls under: https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing
Yes, OP has a verbose way with words and grammar. On a site like Hacker News that shouldn't be that weird, and accusing people of using AI without a smoking gun hurts culture and discourse far more than doing nothing at all, which is why I'm passionate about baseless AI use accusations. There are more than enough smoking-gun AI-written comments you can flag/downvote respectfully.
