I liked George's article, especially this thing about the "insect preserved in amber".
The odd insect has crossed my path as well, e.g. one evening in France, where I encountered someone from a country X who had lived there with his French ladyfriend for a whole year and still hadn't taken the trouble to learn any French. She felt she had to translate the entire discussion for him all evening.
But kiore has a valid point, I think, arguing that English is a useful tool to simplify communication - to a point.
It's up to everyone, isn't it, to decide to stay dumber longer?
The advantage to be clever is that you can always play dumb - the other way it's not so easy.
