The way we are making leaps and bounds regarding technology I wouldn't be surprised. I can see the day when we just all upload ourselves.
I doubt we will upload ourselves but we will sit back in a room and have a avatar do all the work for us as we turn into vegetables.
I think you're close to my age. Go you remember an old song called In the Year 2525? It may just be prophetic although a couple hundred years off.
I would seriously only want to upload myself after I had lived my life. Think of it - getting to start a new life whenever a new game comes out you want to play. Being around to see your great, great, grandkids and offer them help and guidance in their lives and seeing them all grow up while you still get to have fun and spend time together. It would be amazing!
How usable is virtual reality? Virtual reality is taking over ever more areas of our lives, so it is important that virtual worlds offer high usability. Until now, the only way to check was to conduct tests with volunteers -- time-consuming and cost-intensive. A new technology automatically detects many problems with user-friendliness and usability in the virtual environment. Source 1l.
