The decline in quality and accuracy was just too much. As an English speaker learning a handful of other languages and concentrating on two, it was interesting to me that the first real noticeable patterns of errors and general slop were actually on the English side. Increasingly obtuse questions or statements, ok fine, I will spit those back in French or Spanish with good accuracy. I don't have any issue whatever with the occasionally-dark humor or the gender related topics that might push others' hot buttons, and I appreciate the occasional foray into curious stories and situations. But... over the past year there has been an increasing level of nonsensical AI-generated questions, erroneous answers accepted, multiple correct answers, etc etc... and it's obvious that no actual native speaker looked at a lot of the new content -- either from the native or foreign perspective. A couple years ago there was an increasing level of having to hit the button for "You should have accepted my answer." But for the past year, it's become a daily occurrence to have to hit the button for "You shouldn't have accepted my answer." The latter is a clear indication of AI slop and drift in the language models, and lack of QA. Real human QA is not optional, and Duo has apparently dispensed with it entirely. The result is gameified garbled nonsense. Playing the game was fun for a while (seriously, still in Diamond league for more than four years straight), but the goal is language learning not to compete with other stupid little games on my device. Feh. Done.
