That is the only end game I would consider to be a full implementation of machine translation on par with human capabilities.

In cases where there is no direct equivalent or even an appropriate localization we usually resort to giving a long form explanation. If the machines can do that, they've won.

I can't see the current techniques getting us that far. It's going to require some new, creative thinking to really push the envelope.
