Comment by panda-giddiness

I don't think someone needs to be a (former) string theorist to have an informed opinion on string theory, but I do think they should at least have a physics research background. Like, if someone can't explain what second quantization is, then why should I care about their opinion on string theory at all? There's just not that much room for a discerning conversation. (With the obvious caveat that I have different expectations for a real-life conversation than a discussion forum.)

Our grandparent is sort of the perfect example of an insight-free comment: confidently claiming string theory is useless (without supporting evidence) and then claiming (more like imagining, since there's again no evidence provided here) that an LLM would have abandoned such a research program long ago. What's there to discuss? The comment is based on a made-up scenario; it is, in other words, pure fiction.
