“You’d be surprised how common the name Doug is across worlds. Oh, some spell it ‘Dug’ or ‘Duhg’ but it’s always around. Regardless of local linguistics, parents eventually start naming their kids Doug. I once spent ten years on a planet where the only sapient sapient life was a group of pancake-like beings that expressed themselves through flatulence. And I kid you not, one was named Doug. Though admittedly it had a very distinctive smell when the word was “spoken”. Doug is the naming equivalent to convergent evolution. And once it arrives, it stays. A linguistic Great Filter; a wake up call. Once a society reaches peak Doug, it’s time for it to go sit in the corner and think about what it has done.”
