> you'll struggle to find someone without a genuine fondness for it
I'm such a person. I realize that any kind of preference I have for the language that I grew up with is an accident of birth. It helps to be part of a country that is so small as to be irrelevant in the greater scheme of things. Life doesn't stop at the border and if you want to be active at all then you're going to have to interact with people speaking different languages. English, German and French to begin with, and maybe Spanish, Chinese and one of the Slavic languages after that.
I think English is here to stay in a way that Latin never was, the digital repository of English text is absolutely massive, unless you want to limit yourself you simply have to speak English. When there was no internet that meant books and once the printing press was invented and books were no longer in very limited circulation (and reading and writing became more common skills) written culture really took off. The Roman empire is what drove the spread of Latin and once the empire collapsed it took Latin with it, with the exception of some niche uses (science, mostly, and religious texts).
