Kurtzman has been boasting about the upcoming Mandalorian style AR screens television Trek will be getting soon. They should be perfectly capable of making Yorktown style backgrounds next season.Yup, I know.
Don't get me wrong, the Federation HQ looked nice, but definitely NOT 32nd century style (and that flying rain forest looked a bit tacked on).
I posited before that the Federation HQ would have been cool if it was located in a Starfleet constructed Dyson Sphere (or Dyson Swarm) or a 32nd century style Yorktown starbase with millions/billions of people living there.
