I don't think I disagree with you in principle, although I think these issues also apply to humans. I think even your particular example isn't a very far-fetched conclusion for a human to arrive at.
I just don't think your original comment was entirely fair. IMO, LLMs and related technology will be looked at similarly as the Internet - certainly it has been used for bad, but I think the good far outweighs the bad, and I think we have (and continue to) learn to deal with the issues with it, just as we will with LLMs and AI.
(FWIW, I'm not trying to ignore the ways this technology will be abused, or advocate for the crazy capitalistic tendency of shoving LLMs in everything. I just think the potential for good here is huge, and we should be just as aware of that as the issues)
(Also FWIW, I appreciate your entirely reasonable comment. There's far too many extreme opinions on this topic from all sides.)
