To your actual point, the people that would take the landing page being written by an LLM negatively tend to be able to evaluate the project on its true merits, while another substantial portion of the demographic for this tool would actually take that (unfortunately, imo) as a positive signal.
Lastly, given the care taken for the docs, it’s pretty likely that any real issues with the language have been caught and changed.
No they don't. The text is very clearly conveying what this project is about. Not everyone needs to cater to weirdos who are obsessed with policing how other people use LLM.
Author would, indeed, be wise to rewrite all the text appearing on the front page with text that he wrote himself.
the scs.stanford.edu domain and stanford-scs github should help with that.
