What if you copied your self to a machine and the machine decided it didn't want to have anything to do with you and your wife? What if it fell in love with another machine and they ran off to Tahiti together? Or to Mars, or Jupiter? Could it demand child support payments from you until it reaches 18 years of age? Could a copy of yourself enter into legal contract for you or on your behalf, or would it exist as a completely free and independent entity? If you saved yourself every 5 years or so, would the earlier copies have to be destroyed, or would they continue to live and grow on their own?

Sounds like a good premise for a sci-fi story.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
