Fifty years ago, some of today’s technologies were considered impossible. Here are future possibilities most people consider impossible now:
Circumventing death and disease. Nanotechnologists today are making things that do the work ever smaller. Perhaps thirty years from now, shouldn’t it be possible for us to consume millions of microscopic computers, each of which can grasp, move, and communicate? A cloud of them would live permanently in our bodies, fixing whatever needs fixing. We could direct them to make our biological age younger, permanently, but without diminishing the knowledge and judgment we had accumulated at the older age. I’ve never read science fiction, but I don’t consider this impossible.
Einstein proved some of Newton’s views wrong. Why couldn’t some of Einstein’s views eventually be proven wrong? With the help of extraordinary robots, mankind might learn to travel faster than the speed of light. People and things would be able to travel billions of light years in a flash without deterioration.
Developing this tricky maneuver would probably take longer than thirty years. But with people continuing to have children and not dying, things could get testy without some means of escape.
If we can’t find another planet similar to earth, we might create one. It would be fun to see how the robots accumulate many cubic miles of white-hot iron at the core. Building another earth would cost a little extra, but anything’s possible.
