Yes, because if a human didn’t do it, how will we know of the translation is free of mistakes? /s

Professional translators don't throw around the word "impressive" like that.

You don't, yet I still stand by my work.

I translated some books up to four times as I refined the process. The default behavior is repeatedly to not attempt to translate text it can't resolve for whatever reason. AIs do have a tendency to hallucinate, and I expended a lot of effort on minimizing this problem to the point it can be considered mitigated.
