Based on Science we already know that we are basically conscience and body. Our physical body is just a space suit designed to survive the earth environment. We need a body protection when we are several miles away from earth troposphere.
I hear so many debates about “Artificial Intelligence” on “Artificial Body”. For humans to survive in Space-environment we would have to change this body to something that can survive without any food and water, as a result not producing any bio-product (sorry potatoes) and in addition these body should be able to resist and endure the most adverse environment. A body that needs only Electricity as a font of energy.
With a future advanced technology in addition to currently one available, we can have an Artificial Body. We could keep our current appearance or have choices of a variety shapes and colors of body. Be able to taste food and beverages on social events. Have a Sense of smell; be able to feel the wind and the water-running trough the skin. Have everything on a super body.
Our current technology in space ship propulsion is very limited and its not possible to travel with speed of light, even in the near
Future and most likely our biological body could not resist the speed of light.
With Artificial Body, humans could extend their life span into a several hundred years. With this in mind, we should no limit the space traveling to “ how long” but to “ how Far” the distance we could go. How perfect for very long missions.
It doesn’t make any sense to start a very important space mission that cannot be finished in our lifetime expectancy.
We should focus on developing an “Artificial Body” for our Intelligence and not creating fear of the Unknown as I have heard from some scientist and some philanthropist.
Apart from the Moral and Ethical Issues, we should be worrying about saving our species.
