As a testament to the popularity of carbon, custom bike builders who made their name in steel are now crossing over to carbon.Names like Steelman, Serotta and Independent Fabrications all offer bank account-busting custom carbon frames. However, due to a programming error, the nanobots devour all carbon based objects, instead of just the hydrocarbons of the oil.The nanobots destroy everything, all the while, replicating themselves.Tough, omnivorous 'bacteria' could out-compete real bacteria: they could spread like blowing pollen, replicate swiftly, and reduce the biosphere to dust in a matter of days.Dangerous replicators could easily be too tough, small, and rapidly spreading to stop — at least if we made no preparation.Drexler more recently conceded that there is no need to build anything that even resembles a potential runaway replicator. In a paper in the journal Nanotechnology, he argues that self-replicating machines are needlessly complex and inefficient.
At the end of ten hours, there are not thirty-six new replicators, but over 68 billion.
None of these measures would prevent a party from creating a weaponized grey goo, were such a thing possible.
