If it seems obvious from where you are, then the target audience must not be where you are. In particular young students definitely lack context to critique and a big anonymous sampling like this is a great exercise.

I can understand not realizing that ChatGPT would give a bunch of similar sounding article titles to everyone, and I can understand being a little embarrassed that you didn't realize that. But why would you feel a "personal stake" in the output of an LLM? If you feel personal stake in something, you definitely should not be using an LLM for it.

Because you thought that you had collaborated with the LLM, not that it had fed you ideas. Have you and a partner both believed you contributed more than 50% of a project's work? Like that.

Again, the statement "if you feel a personal stake in something, you definitely should not be using an LLM for it" is a learned response. To folks just forming their brains, LLMs are a natural extension of technology. Like PaulG said, his kid was unimpressed because "Of course the computer answers questions, that's what it does".

The subtlety of it, and the "obvious" limitations of it, are something we either know because we grew up watching tech over decades, or were just naturally cynical and mistrusting and guessed right this time. Hard earned wisdom or a broken clock being right this time, either way, that's not the default teenager.
