Natasha Vita-More is one of the people whose ideas on full body prosthetics I have fully embraced. Of course, I do not believe we will be able to go directly from our current bodies to full body prosthetics without a bit of interim steps.
There are people who are horrified by the idea of life in virtual reality, or even life with an artificial body with vastly improved looks and abilities. I’m not one of them.
I see life in Virtual Reality as opening new doors for deep space colonization. A brain, after all, takes up a lot less space than a body, and Virtual Reality provides a relief from the “Cabin Fever” that a long space journey might otherwise impose on travelers.
All this is before we start discussing the huge varieties of nutrients required to keep the body alive. Without having to worry about anything more than the brain, the weight requirements for food and water drop significantly, while the apparent “Choices” rise significantly. After all, it wouldn’t matter what “food” or “drink” the brain thought it was experiencing, the computer would deliver the same nutrients and trigger the appropriate receptors in the brain to generate the desired experience as required.
The advantage of this scenario is that the 70% of our planet currently covered by seawater could be converted to a virtual habitable community, where humans lived in luxury virtual homes connected to surface dwellers through satellite communications and shared remote avatars. Perhaps these avatars would simply have a display screen in place of a face, so that normal, biological humans could tell who they were talking to.
Jobs performed by an autonomous computer, of course, might use the same remote avatars, but have a face which was of a predetermined color. Green comes to mind.
That’s right, I couldn’t resist the temptation to suggest we create little green men. Sue me.
