I am currently reading Michio Kaku's book “Future of the mind”. Michio Kaku is a string field theory physicist who has written a lot of books on the future of science. Since the future is fluid and notoriously hard to predict we are always in doubt whether any claims about can be taken seriously, but Kaku does his best to give his statements some foundation. He talks to fellow scientists in the field who tell him what is already possible and what lies immediately ahead. That's the easy part. It's of course much harder to predict what lies further around ahead of us. Maybe not so much the technology itself as the way it will come to us and how it will be applied.
Back to the technology of duplicating minds. It's the hardest part, but in a way the most interesting one. It will start with attempts to create a backup of your own mind. A backup that can be restored in case of emergency. For instance when somebody throat is cut and he dies before the ambulance can come. It is possible to repair the body, but usually not the mind. However, with the backup we can do it. Of course the victim will only have memories from the time that the last backup was made so it would be nice if the backup was fairly recent. This might induce people to backup themselves regularly. Say once a week, or when storage space and energy consumption allow every day. I can also imagine that people don't want to delete their backups. After all these are ultimate selfies. I can imagine that before long people make a selfie every day of their lives from birth to death. The mind library on which the selfies are stored does not need to be earth. The moon is maybe a better place, because it has plenty of energy from the sun and storage space. What do we do with all those selfies? Suppose I have 40.000 days to live and a selfie is taken every day. There are Jos-1, Jos-2, Jos-3 ….Jos-40000 in the mind library. They are all Jos but in different stages of life in different circumstances. If they are in the mind library lying passively as recorded data they might be consulted as a kind of archive at best, but things change if selfies can actually have an own life in the mind space.
The bold and the beautiful
How would the bold and beautiful look like when there are 40.000 copies of Ridge and Brooke each! Some might like each other, some hate each other, and some might even want to kill each other. If one of the Brooke copies kills a Ridge will only that copy be held responsible? Might it be so that also others are punished in order to prevent repetition? Relationships can be a mumbo- jumbo without any limits. The number of copies in the mindspace will just grow. You could have a relationship with your great-great-great grandmother. After all in the mindspace you don't grow really old. You just are.
How will society look like in these circumstances? The glorious leader of North-Korea could create 50 million copies of himself to keep track of his corporeal slaves. Other members of the elite might have several copies of themselves while others have none. In democratic societies there are also problems. Do the rich, famous have more copies than anyone else? Is it one copy one vote? Or one personality one vote? Or are the concepts of democracy versus dictatorship not valid any more when society becomes a fluid form of deeply interconnected entities?
Conquer space with our minds
When this happens it is also a time for serious space exploration. Instead of beautiful romantic startrek spaceship we will send a black rock into space. It will contain our minds and some equipment to build a home for new minds. There will be no need for windows, screens or computer consoles. There will be no need to go through great lengths to keep human bodies alive in space. No need to make planets suitable for colonization. What you need is just a sturdy storage of minds that can withstand enormous acceleration towards light speed. This is way we will eventually travel towards the stars. It's the way advanced brain technology will open up for us.
