I presented a "lighting talk" (8 minutes) at the New Librarians' Symposium 10 (NLSX), 29 July 2023, online. Here I provide the footnoted paper (including additional material). No slides this year, because they aren't interesting and because of technical difficulties they didn't show up anyway. Online conferences are problematic.
Talk is Creative Commons Zero, so go nuts and claim it's all yours if you want.
