The future will be an age of wonders, wonders that will describe their terms.
Those wonders will come to us, probably most unexpectedly.
They will surprise us, with delight.
At some point, humans will not live in cities anymore. Not the ones we know today.
They will emigrate into new structures.
Those structures will make sense to the ways of life that will be adopted.
Humans adapt quickly.
History of human habitation:
1 Caves or cave-like sheltering places
2 Tents, houses or house-like structures (wall + roof)
3 Several houses, villages, castles
5 Megacities, urban sprawls
6 Unknown; eventually massive realignment/repurposing; massive + flexible superstructures, absolute /\ invisible architecture
All we can think of is possible
There are no boundaries to thinking
