I'm not sure whether I constructed my argument properly, but it was about the average person being less productive due to working in a language that isn't second nature to them. German probably was second nature to von Neumann. In other words, by native I didn't necessarily mean the one and only mother tongue.
Sorry. No. Your argument was well-constructed. I have acquired two other working languages and it took about 15 years of regular work. I appreciate your point. Still, speaking more than one language seems to have benefits for general intelligence. So perhaps it is both a blessing and a curse.
