They are miles better than the ordinary machine translators. That's all that matters, because I can't afford a personal human translator to browse the web.
Human translation is obviously better, but not by much, especially on the web. I know because I'm testing LLMs for pretty complex translations all the time, in languages I understand well, and two persons occasionally communicate with me in my native language using an LLM. It's accurate enough to not have any troubles, especially if you don't prompt it naively and use a strong multilanguage model. It's not the same as slop generation, as the input is from a human.
That guy reacted to them ignoring him and overwriting his hard work with a worse version, which is terrible but not related to the point I'm making.
