As more and more movies like Spider-Man: Into the Spider-Verse and Interstellar are being introduced, it brings up a whole new discussion on the parallel universe idea. Different dimension could exist at the same time. Ernest Cline’s Oasis universe in Ready Player One strongly illustrates this. In his version of this universe where different planet exist, we as players(audience) could travel from one to another. 2D characters can exist within 3D space and vice-versa.
So what happens when everyone is a creator? There would probably be no audience. Or, everyone could still be the audience. We could totally have more than one roles in life. The problem is how to visualize all these content.
