I can't help but feel that before doing something like this we should find a way to prove that the answer to the Fermi Paradox isn't berserker drones or some super advanced civilization that is actively hunting down and destroying all competition or something.
Not that I think that is the answer. Personally I ascribe to the "space is freaking big" solution to Fermi, but if it IS berserker drones then this is not how I'd want to be proven wrong.
