OK, I have to ask.
We've been hearing about all these super-efficient, super cheap,
_theoretical_ cracking devices for years now. Surely supporters of US
policy have been ridiculing these assertions for as long as they've been made.
There are many, many companies and individuals who could join together to
bankroll these things.
My question: when will someone produce one? If I were looking for to
produce evidence to support decontrol, I'd be working on one now.
Just wondering.......
