@ireneista @aeva @rygorous just an intuition but i feel there's a push-pull between at least two different factions: the "save energy, move mouth/hands less" faction (you see their handiwork everywhere), and the "we recognize elevated status in society by the use of multisyllabic technical terms under the guise of aiming for enhanced expressive precision" faction.

in addition, language is not only used to foster understanding, it's also used for demarcation. youth slang is mostly this.
