My guess is the French language will prevail in Québec if and only if we make it necessary to outsiders.
That means we must be creative, punchy and the economy of Francophonie must be steady enough.
Otherwise, English-speakers will think French is helpless. I read many comments going like - finally something that makes me want to learn French!
As if they hadn't found out before...
That's because many of them are clueless and don't know us, and we're not super active in stuff like show business, for instance. We have nothing like any Hollywood industry in the French-speaking world, while it is obviously a handy tool to serve their global communication and propaganda.
Moreover, we don't really have demography on our side, unlike Hispanics.
Some talk about French-speaking Africa, but it's still harshly impoverished, so it's been hard to make something influential of it to date.
I don't know whether the Africans will give up on French. My feeling is that they like the culture and it's been some part of them already, so they may remain faithful to the language, unlike what some say about that.
I don't see them speaking Russian instead.
I just wish they were better off. It would make it easier to defend our language on the global stage.
For now, it's up to France, Québec and the French-speaking bits of Belgium and Switzerland to keep it up.
But it's important to keep faith in Africa because they're obviously much of the future.
