>And because AI does not comprehend what is written in the sentence, it will let it pass. This is demonstrably false. GPT4 can easily expound upon, rephrase, simplify, clarify and correct things it has said when prompted to or provided new information. That cannot be done without some form of conceptual understanding of what was written. The issue here, which is both obvious and covered in the article, is that they aren't using AI trained on the target languages. They are translating (imperfectly) to English first and then trying to moderate that. But, frankly, that is a difficult task for a human. Idioms, slang, coded speech (analogous to whinnie the poo=Xi) are all going to slip through the cracks even with a human.
