I can see a history book written 500 years from now. “Only the morons who lived in the 21st century were stupid enough to turn gender into one of their ‘gray areas’.” No geniuses lived during this century. Just a bunch of morons who all thought that they were geniuses.” The humanoid units living on this planet right now definitely have to be the dumbest to have ever lived.
I recall a Twilight Zone episode where a family is speaking English and eventually given advance warning of impending doomsday. They get onto a spaceship and head for a safer life on another planet. At the very end, we learn their destination is Earth.
