Predicting words != LLM. There's different methods of doing it, current LLMs are not necessarily the most optimal method. The paper states this as well, > This computational organization is at odds with current language algorithms, which are mostly trained to make adjacent and word-level predictions (Fig. 1a) I feel like you're suggesting because humans != LLMs then humans cannot be doing next word prediction.
