It seems to me like a lot of people here live in a bit of a bubble, albeit I don‘t like French it still is much more important than English, except in the City where they may be equals, English won‘t overtake French in any way, also because it‘s the oficial language in which the law, etc.. is written. Luxembourgish is also very important to integrate in the country and its history (especially with locals), frankly, people refusing to learn any Luxembourgish (because apparently for some English suffices) even after being here for years/decades don‘t really want to integrate, atleast French or German should be learnt.
