answer:I think it is a massive deal, probably not for us, but for the next generation. I could be wrong, but the way I see it, this is a big step towards humans controlling matter in a way that has never been done before. I am thinking along the lines of Star Trek replicators. With this discovery, the work on the genome, the work on nano materials and quantim physics, makes me think that this is a major step towards humans controlling atoms and all things small as we have been controlling wood and stone for the past few thousand years.
