I believe that in this century, we will be able to digitalize human beings. This will be the key to both humankind's survival as a species and our exploration of space. The digital society would have no famine, no plagues, and no poverty. This would solve all major problems we face today. Digital humans would even defeat death. Sounds like a wild sci-fi idea? It is, but then again, smartphones were also a wild sci-fi idea a few decades ago.
