Well, I don't see what this has to do with Buddhisim but....
Some Science Fiction writers have used a plot in which, in the distant future, what are essentially immortal beings exist.
This is done by somehow transferring one's conciousness into an artificial being created for that purpose...and artificial body not of flesh but in fact a construct created for that purpose.
When that body began to wear out...as eventially it must...then a new body would be created and the conciousness would be transferred into that new body and the old one either destroyed or perhaps recycled and reused.
Also if any body part was somehow damaged, it could be removed and replaced with a new "unit".
It has even been suggested that such a condition will be what we will find if we ever do meet a really advanced intelligent alien lifeform...because they will have evolved beyond the physical body humans have now live in such an artificial construct...transferring their conciousness when the old body begins to wear out into a new body.
It has even been speculated that this is the normal condition for any sufficently evolved intelligent lifeform...the biological body we have as human beings is merely an early imperfect biological stage which will ultimately lead to a nearly immortal non-biological stage.
But all that is just Science Fiction speculation, and can't be done today or for any forseeable future.
Come to think of it...what implications does that possibility have for the concept of Karma or Rebirh for Buddhists?
Shame on you Shakyamuni for setting the precedent of leaving home.
Did you think it was not there--
in your wife's lovely face
in your baby's laughter?
Did you think you had to go elsewhere (simply) to find it?
