[That's some weird phrasing.] You don't look that old...?

Um. Well, I know the big differences are that we grow most of our protein, because eating animals is gross and cruel. We have anti grav technology, plasma weapons, advanced artificial biological replacements. Humans travel interstellar distances using skips and jump gates. Most people aren't giant assholes about sexual orientation or gender or any of that stuff any more.

Oh. And we use uterine replicators instead of making women get pregnant because that's really dangerous and medically unnecessary.
