I’ve heard a lot of Gen Z people confuse dystopian and utopian. Usually I don’t care about “correct” language at all, I’d even argue languages that change are alive and changes are often invisible to those with rigid or discriminatory thinking. In this case the confusion seems almost deliberate or directional as in having an origin in some media where it is confused heavily though.
I never would “correct” a person IRL about this, but I am really confused how it is possible that several people can make the exact same error. Are the assigned meanings to those words changing?
I’ve not seen the confusion myself, but there are a lot of visions of utopia that are dystopian. When you have a fascist (techno- or plain old Nazi) describe utopia, it often sounds very dystopian. I can see getting confused based on how they see it used.
