If we discover both room T+P superconductor and viable fusion on year Y, at which Y will we see the first city like this :

• Resolve N/A if superconductor and fusion are not achieved in the mentionned 1 year timeframe

• Other picture implicit features that the city must have to resolve positively :

  • Must be sustainable and made out of sustainable materials

  • Must more or less merge with nature in shapes and functions

  • Must include all features to sustain long term inhabitation

  • Does not necesarly have to be shiny white (but it would be cooler).

Ultimately resolve to my personal appreciation of enough similarity with the picture and implicit features.
