I love the English language, and maybe now, also due to the diffusion of Internet it is the best choice; predominance of English (at least in Europe an USA) over French, is quite a recent fact from an historical prospective, so as History always offers quick changes, we might expect some other language to compete with English other this (maybe) predominant position.
I hope the many languages in the world will stay and develop, even if in the future more and more people will happily share a common language, thus increasing their capacity to quarrel and dispute with good satisfaction, and if we or them will be lucky enough, even without weapons!
A proposal to Mr. Dreyfus who asked this, and to the many writers and readers: please make sure you'll have some spare time on the evening (GMT) of Oct. 7 2025, to further discuss the matter over here. I'll bet 10000 ITC that many of us (like me) will need a Chinese interpreter -- don't forget your Italki password !
