Imagine seeing the trends in books throughout certain time period, wars, etc. Or larger trends over the history of all written works. Or all kinds of other neat and useful information that can impact decisions we make today. Do you think all analysis of things you aren't personally interested in is useless?
I hate "did you even read my comment" replies, but again, you're pitching me on "trends throughout a time period", "larger trends throughout history" and "all kinds of other useful information that can impact decisions".
I don't think a person without interest in literary analysis would make this comment. On the contrary, I'm specifically calling out building non-sensical tools with little practical uses because the author of the tool does not engage with literary works beyond the most superficial layer. And because I don't believe quantitive analysis of art is benificial to culture and society, but that's a broader subject.
