@cstross @Gargron My (very not translator) impression is that human translators who have worked from rough machine translations, say that it’s harder than just translating the text.
Also, today I was in a work info session, where the talks were translated by some MS PoS thing, from Finnish to English. The results were horrendous, if hilarious. It might get better but I don’t really know why. Good simultaneous interpretation is kind of a human-level problem, really. Context matters!
