bidirectional inverted commas, negative parallelism, short punchy prose, dot point listing ... these language techniques are consistently present throughout. whether this article was written by AI or not, its structure and style utterly screams of AI.
it is understood that LLM style is derived from human style, and that LLM style is now influencing human style. this doesnt make it any more obvious how to type an em dash or bidirectional inverted comma. nobody outside of academia or publishing uses these techniques of their own accord, only LLMs do. thusly i optimize out your chicken/egg conditional as it seems like a redundant branch - if something looks like AI, it's probably AI, so why does it matter what the AI was trained on?
