One day the Earth will be a sphere made of little spheres that have even smaller spheres orbiting them which also have even smaller spheres orbiting those. Your home and possessions will be immaterial and all of your contacts and destinations are immediately accessible via quantum entanglement.

We will have mined and refined all of Earth into essential components for a greater mechanical and technological whole, culminating in an intergalactic sentience that travels the universe replicating itself until all material is localized and compressed into an infinitely dense cluster of atoms. Uh-oh.
