Question: Do you think that the world will have a tech-based surface one day?

Hi! We need space on the surface of the Earth for all the plants and people and animals. But some things are going to become more tech-based. I hope that more efficient solar panels will be developed, so that we can have smaller panels generating more electricity. There are interesting development in paths and roads that can also generate electricity due to movement across them, which could be used to power lighting. There are lots of things which we could still develop, and better technology will help us if it’s used for useful applications.
