Let's recap:
> I launched the prosecraft website in the summer of 2017, and I started showing it off to authors at writers conferences. The response was universally positive, and I incorporated the prosecraft analytic tools into the Shaxpir desktop application [...]
And he goes on mentioning that some authors even reached out to him to get their books added.
Unless you are accusing him of lying or unreasonably overstating the response he got ("universally positive"), for which I really don't see any indication, then a statement like "finding a few writers that like this is trivial" is not a good faith engagement with this topic/conversation.
“Everybody not agreeing with you represents "chauvinistic SV attitude"?”
…wasn’t very good faith either as it’s unclear whether the writers share the same belief as some tech people that AI and humans doing stuff are the same and use that idea to further a pro AI agenda as opposed to them just finding a useful tool to incorporate into their workflow regardless of the underlying technology or politics. Your response assumed the former and paints OP and attacking them with his statement.
No, he didn’t say anything about them. People side against their interests all the time, finding a few writers that like this is trivial. Are those people the majority opinion on this or are we just trying to prove how wonderful this technology is?
