possible advancements

I think eventually will be able to live in a completely digital world if we so choose. It would be like the role playing games or sims but instead of watching your character you could be your character. This type of immersion could bring about a lot of interesting things like training for soldiers, or cops. People could also go on vacation without leaving their house. The problems with this would be some people would prefer to live in the virtual world compared to he real and this could severely impact their lives.
