If that actually does happen. Do it in conjunction with backing up the brain. Thus achieving true immortality.

Have bodies that are engineered to live forever, but accidents abound. Should anything happen to you, they'll re-clone you and restore the last brain backup.

Like the cylons did in Battlestar Galactica.

Imagine living for 10s of thousands of years and the only way to truly die is for your genetic material to be disposed of and the backups wiped.

If tech like that were available. I'd happily sign up. Travel the stars and explore the unknown!
