AI has completely killed Google Translate. It is significantly superior in every way.
GT often uses the wrong word or changes the tone of a message. AI always gets the intent right and always seems to use the most appropriate words given the original intent/meaning (or at least something way better than what GT does). And, whenever there is doubt, I can argue with it, so AI is happy to explain the nuances and differences between the possibilities.
Edit: I recently had to send a semi-formal email requesting something from a government employee in a different country (using a language I'm a beginner at), and AI was immensely helpful in getting the right tone (neither informal or too formal) and everything else right. The Google Translate version of what I had originally written was miles and miles and miles worse than what AI helped me craft.
True, but Google Translate was already "AI". They previously used LSTMs. And before LSTMs, it was ML-like statistical translation.
