In various threads, we are discussing mind upload to a computer. There are some confusions and I would like to state my understanding of such a task. Comments are welcome. Once we have a technology to transfer the program and memory of a person (not anytime soon, but may be in the next 150 years), we are exploring the best use of such technology. Assuming that we can create a virtual world of cities, robots, transporters, food etc., we can upload minds to that environment to populate the virtual world. Then my proposal is simple. As people retire, they can decide to move in to the virtual city, at first temporarily using a plugin device and then permanently when their biological body is at an end. Children of those who move to the virtual retirement can visit by pluging in to a mind interface port. When the children grow old and retire, they too can move in the same way. In the beginning, the computers will be very large to house such a virtual community all networked to other communities around the world. As technology progresses over time, Each family can maintain their virtual family all networked to other virtual habitat. Since computer density doubles every 12 to 18 months, it should not be difficult to house several generations in the system. Oh!, one benefit in the virtual world will be no real body and therefore you can eat anything without gaining weight and no sickness (except if somebody pulls the plug - you need SRAM memory to revive Please Register or Log in to view the hidden image!) - unless it is programmed differently. So what do you think?
