What's your take on it?
I personally can't wait for it to be mastered. Just imagine the possibilities - being able to create at atomic level *any* known material from an energy source. It's even possible to create new "super materials" such as incredibly light-weight and flexible materials that are stronger than steel etc.
Being able to produce any form of food with very little energy input - could be an end to famine in certain countries. Hell, it could be an end to currency as we know it! Who needs currency when any material can be produced like magic? I know that's an extreme case but I suppose it is possible.
Computer chips more powerful than the fastest consumer CPU at the moment, but no larger than 1mm in diameter! Tiny machines using these computer chips to guide them around your body and repair internal organs. It sounds impossible, but it isn't.
I'm definately not buying into the whole "grey goo" theory of tiny little robots gaining an awareness and taking over the planet though.

Although I suppose it is possible for some loony with a good understanding of the technology to form a colossal(?) army of killer robots and TAKE OVER THE WORLD!!! BWAHAHAHAHAHAHA
So what are your thoughts on the matter? Do think it's a good thing, or a bad thing?
