"We even have the learned ability to accurately predict the next word in a sentence, even when we do not understand the semantic content of the sentence itself."

yes, and I dont think its a good thing for humans, as this is the main reason why people still try to make sense of content that's not well defined(poor rigor), even though they think they're doing meaningful work for the field. Take philosophy, for example. Those "big questions"(do I exist...) lack proper meaning for deduction
