Nanotechnology, is bio-matra
Micro-nanobots, in themselves, are an intoned by influence self intelligent cluster community.
These bots, have their own needs and their own swarrm realization, as to what is necessary for them to do, for survival or the end of the mission to occur.
A virus, is a biological design, that inherits, the duties design, function from the evolution of parents, from which they came.
It is possible to combine both nanobots and viruses as one entity.
There is a light of reason, which occurs, that is their paths direction, as to how they should be, either with an overauthority present, or no overauthoerity at all.
Natures, in her evolutions of two stuffs, shall provide the proper f direction, once the clairency of wants and needs, has been decided by the nano-virus colonies.
