Earlier quoted context omitted.
Calling it text autocomplete is played out and really just makes you look bad at this point.
It's literally text autocomplete. You can dress it up however you want but it takes input text and outputs the most likely next sequence.
You are obviously right and I see examples of it everywhere.
E.g I asked Claude opus 4.7 (the latest/greatest) the other day “is a Rimworld year 60 days?”. The reply (paraphrased) “No, a Rimworld year is 4 seasons each of 15 days which is 60 days total”.
Equally, it gets confused about what is a mod or vanilla since it is just predicting based on what it read on forums, which are clearly ambiguous enough (to a dumb text predictor).
