So does Rank have privileges in the future? For some it does because for example Data having to call Deanna sir because she was a commander and he was only a lieutenant commander. Even though she was just a counselor and he was chief operations. And I believe it was also hinted that he would have to follow her orders as well to some extent. But some say it doesn’t for example senior chief petty officer (enlisted) O’Brien ordering around Ensigns since he was chief of operations/chief engineer.
