'Model rot' refers to AI language models degrading over time — either because the model is retrained on AI-generated content (a known problem), or because users perceive a deployed model has become worse since launch. If your teen talks about model rot, they are engaging with AI-quality debates. Useful media-literacy vocabulary; underlines why critical evaluation of AI output matters.
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
