My pet theory is that multilingualism multiplies the delta in natural talent: gifted people become stellar writers/talkers, whereas less talented people might suffer from career-inhibiting deficiencies in all languages and often would have been better off focusing on a single language.

I'm far from considering myself multilingual, but if I could somehow trade a part of my English skill for a magical boost in my native language I would gladly take it: half of my English abilities would still be plenty for understanding the occasional stackoverflow post, this place here would be just fine without my contributions and ordering food at a restaurant is actually easier when you can fully embrace the "helpless tourist" level. In my natural language, one level better might be the deciding difference between writing as a necessity and writing as a selling point.
