I'm wondering what the opposite of a paean might be, or if there's such a word in English. I thought there was, but I can't think of it.
The example I'm using is that Ernest Cline's Ready Player One. It's a novel about a dystopian future where people spend all their time jacked into a virtual reality called the OASIS, neglecting nature and choosing not to live in the real world. Cline's work is a warning against the direction in which we may be headed. This seems to be, to wit, the opposite of a paean to technology. What would this be called?
