Maybe we can. If you assume the mind is the constant in our reality - opposite to the traditional view, in which the physical world is supporting the mind - then we should be able to move into a virtual one. Maybe we're just layering worlds on top of each other, and old ones can become irrelevant, forgotten and disappear. Our current world could be just a virtual one, built on top something long forgotten, and will in time vanish when we move into Minecraft.
