For me, it would simply be one where humanity finally wakes up and realizes that we are all one big community that is extremely similar to one another despite what many of us may think and that we all finally just get along and stop fighting and forcefully controlling each other for stupid reasons. It would be a society where the first response of any individual or organized group/establishment when confronted with something unusual, unknown, or even seemingly threatening wouldn't be to suddenly attack or avoid it, but instead to approach it open-mindedly and with an attitude of empathy and understanding. There would also be no poverty, no bigotry, no other discrimination, etc., etc. and instead humanity would work together to create an awesome existence for us all to enjoy by focusing our efforts in a more creative direction through technological and artistic ingenuity in order to make life more of an actually enjoyable and fun experience, rather than one that is so often plagued by suffering and crushed dreams and hatred and boredom and stupidity and so on and so on. In other words, just a place where humanity actually manages to reach our truly vast and grand potential as the intelligent (well, at least some humans are lol) species we are.
