I liked the article. Part of what he's touching on is actually far more general. Language translation/speaking is just one skill a human can acquire though. For him, part of what gives his life meaning is being able to write a letter or have a conversation in another language, and the fact that this is hard is part of the meaningfulness of it.
When everything we do becomes easy and we can just ask an AI/robot to do it for us, how will humans replace the meaning that comes from skill acquisition/performance?
