And even if we somehow can accept turning the entire population into clones, it is worth noting that the recreation of the data cannot be 100% accurate. The 1/1E9 flaws that may take place in the recreation would lead on to more problems:
- Consistent cloning, due to frequent teleportations, of the minorly errored clone (due to the first cloning) would lead to an exponential shift leading to an eventual mutation that could be severe enough to have the clone not even resemble the original.
- What do we do with the original?
- If we some how accept to atomize the originals once a clone is made, the errors lingering within the clone would be passed on to the offspring, even if the offspring are merely engineered from the clone's genetic code.
What you describe there is commonly known as "cancer".
I think cancer will be cured much sooner than there will be a working teleportation technology(for example just by storing the DNA and replacing the mutated DNA using nanotechnology).
Also the flaw you are describing(10⁻⁹(where did you get this number?)) is big. The error could lead to a displacement of your atoms of about 2(2 m)10⁻⁹ = 4 nm which is huge. The cell membrane is about the same size and would therefor get destroyed and you would die. Until the flaw would be much less(10⁻¹⁰ - 10⁻¹¹) this technology would never get used.
Yes changes may also affect the brain, but since the brain has an incredible power of self repair I don't think this would be an issue. Especially not with flaws only in the region of several 100 picometers.
