This didn’t really happen today, but seriously? The computer is an automated (not great, but still automated!) realtime, inline many-origin-language speech-to-text, text-to-alt-language, many-destination-language text-to-speech translator. These are all hard problems, although text-to-speech is perhaps closer to a solved problem than the other two. But translation in particular has been touted as a possible substitute for the full Turing test.
We live in the future. Right now. And it’s turning out to hold the possibility of being a pretty dang good one.
