"Thus the first replicator assembles a copy in one thousand seconds, the two replicators then build two more in the next thousand seconds,
the four build another four, and the eight build another eight. At the end of ten hours, there are not thirty-six new replicators, but over 68 billion. In less than a day, they would weigh a ton; in less than two days, they
would outweigh the Earth; in another four hours, they would exceed the mass of the Sun and all the planets combined - if the bottle of chemicals
hadn't run dry long before."

• Uncontrollable Nanoreplicators
• Grey goo scenario isn’t an imminent danger•Distant technology•More desirable methods
• Eventually, intentional use possible
