If we accept the argument in Drexler et al (UNBOUNDING THE FUTURE, 1991, p.
259), the only way to stop some demented or feckless brat from reprogramming
his genie to emit meteorological quantities Aum Supreme Truth happy gas, or
pick plutonoium out of the sea and stockpile it for later fun times, is to
maintain strong regulatory authorities which licence users of genies able to
produce dangerous outputs only if these are restricted to sealed assembler
labs or factories. This rather short-sheets the utopian dream of a genie in
every pocket, but I find it hard to see any other way to forestall the Fermi
Paradox.
