Apparently it looks identical to MS Office, so it isn't "better" than MS Office or LibreOffice in a functional sense (arguably less so since it's probably very buggy code)

I wouldn't say it's people (normal people would be using MS Office or LibreOffice most likely) excited that it's LLM generated, though some AI Bros probably are, I imagine some outlets are promoting this to sell whatever the new model is these days. And when there is a lot of news around a topic, it's covered by more and more people (something about all press is good press here)
