I don't know about that. Certainly I challenge the phrase "bad" science
fiction, because it's been done well a couple of times... but that's not
the point.
I know of at least two instances of sub-molecular technology. (1)
artificial atoms; (2) sculpted quantum states. (Unfortunately my links
appear to be broken - sorry, guys! (1) is changing the shape of a
single atom's wavefunction, and (2) is doing some kind of custom stuff
on probability distributions, I think. Anyone have a valid link?)
Not hydrogen-into-gold (does jon have any idea how much energy that
would release? it'd be orders of magnitude more than an equivalent
thermonuclear hydrogen-to-helium), not even close, but it strikes me as
a good reason to believe that nucleus-manipulating "atomic
picotechnology" would be an active frontier once atom-manipulating
"molecular nanotechnology" matured.
What the heck does he - does *any* race with that kind of technology -
want with gold, anyway?
