> They’re more like academic papers (peer-to-peer communication of new discoveries)

This made me laugh because I frequently see HN comments on arxiv papers claiming things like the authors are trying to show off with their math rather than the math just being an effective communication tool. Honestly, if anything, papers are written to too broad of an audience and we get these 10 page papers that could be communicated in 3. I'm unsure if this has been a good change. (Yes, I read the whole comment)

Just because you have access to the text doesn't mean you're the intended audience.

Probably a good thing for us to all remember here on the interwebs where everything is accessible but written for no one
