How fast can medical nanorobots replicate inside the human body?
This is a very common error. Medical nanorobots need not EVER replicate. In fact, it is unlikely that the FDA (or its future equivalent) would ever approve for general use a medical nanodevice that was capable of in vivo replication. Except in the most unusual of circumstances, you would never want anything that could replicate itself to be turned loose inside your body. Replicating bacteria are trouble enough! Replication is a crucial basic capability for molecular manufacturing. But aside from the most aggressive applications, there is simply no good reason to risk manufacturing “fertile” nanorobots inside the human body, when “mule” nanorobots can be manufactured so cheaply, conveniently, and in such vast numbers outside of the human body. Replicators will almost certainly be very tightly regulated by governments everywhere.
