This is a bit far-fetched, but fascinating all the same. As Cassidy stated, the possibilities will be endless, but it is unlikely that ALL of its potential uses will have a positive impact. When a technology is as accessible as this is intended to be, the possibility of it falling into the wrong hands should be a concern. As ludicrous as it is, I can't help but imagine robot armies taking over the world like something out of sci.fi. film. Although that particular idea is a tad extreme, I still feel a bit wary about the whole concept. If this technology is to be developed, I believe that reasonable controls will need to be enforced to ensure that the positive potential is harnessed and the negative consequences avoided.
