The biorobots are made of living matter, they don’t change, they don’t modify, they are not to be completed.
They have an unlimited system of existence; except that they have a closed circuit, a perpetuum circuit.
[...] No comparison can be made between the biorobot and the clone.
The clone is an identical entity, an exact replica, with a limited protective system and with a limited lifetime. Of course, it can attain 11 thousand years, but it is still limited.
