It's been apparent for a long, long time that pedagogical considerations have no sway in the direction of Duolingo. I'm not surprised to hear that they're planning to outsource customer support to AI. If anything, I'm amazed they haven't outsourced all their language courses to AI yet. Those are merely the colourful backdrop to the slot machine business that they're actually in. (Come to think of it, how do we know they haven't?)
Kudos to the mods. I have no idea why a bunch of language enthusiasts should be expected to work as unpaid support staff for a ghoulish casino app.
