The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.

If we attempt to block the development of new technology, we effectively have ensured that the most responsible parties will not develop them.

Nanotechnology will let us build computers that are incredibly powerful. We'll have more power in the volume of a sugar cube than exists in the entire world today.

If you think the technology is infeasible, you don't worry about what it might do and what its potential is.

If you look at the various strategies available for dealing with a new technology, sticking your head in the sand is not the most plausible strategy.

Lighter computers and lighter sensors would let you have more function in a given weight, which is very important if you are launching things into space, and you have to pay by the pound to put things there.
