I am actually pretty sure that the thing described literally isn’t a real job, at least not working for a serious employer. I can’t imagine a company telling someone to sign contracts in a language they can’t speak and somehow try to make a sense of it.
Either it’s their own company and they’re doing something unwise, they are doing it without the knowledge of their superior or their company shouldn’t be trusted with anything.
The point was that „AI helps me translate the contracts I want to sign“ isn’t a good example of „AI increases my productivity“ because that’s not something you should ever do.
