Will “old nanorobots” left in the body cause problems when they eventually fail?
Following most simple treatments, nanodoctors of the 21st century will want to remove their therapeutic nanorobots from the patient’s body as soon as the nanodevices have finished the job. So there will be little danger of “old nanorobots” breaking down or malfunctioning, or causing something unpleasant to happen to the patient after the original disease or traumatic condition has been treated. Additionally, nanorobots will be designed with a high level of redundancy to ensure fail-operational and fail-safe performance, further reducing the medical risk.
