"I say looking at the next 100 years that there are two trends in the world today. The first trend is toward what we call a type one civilization, a planetary civilization... What is English? English is the beginning of a type one language. Everywhere I go around the Earth, people speak English because that is the lingua franca of science, technology, business. They all speak English. It is the number one second language on the planet Earth."
