French is currently unique in that it's the previous lingua franca, so much so that the term for "world language" in English is a French term.

That French is now using loan words from English doesn't mean that it's dying. Have you tried to speak English without French / Latin / Norse loan words? Good luck.

It just means that French is like any other language now, aggressively borrowing from the current world language. Nothing wrong with that.

not quite. The term "lingua Franca" originally referred to a Mediterranean trading language - certainly a Romance language but not French. Yes for a while French was a lingua Franca in the modern sense but the term doesn't come from French.
