"And it made me think - why are these people so insistent, and hostile? Why can't they live and let live? Why do they need to convince the rest of us?"

Same could be said about the anti-AI crowd.

I'm glad the author made the distinction that he's talking about LLMs, though, because far too many people these days like to shout from the rooftops about all AI being bad, totally ignoring (willfully or otherwise) important areas it's being used in like cancer research.
