As to Hugo's question, yes I agree that we don't know everything about them. But that doesn't mean we start making claims about the world ending, all is lost, science is evil, etc. If there were a reasonable degree of certainty that this machine would end the world, then I would agree not to turn it on. But, currently, the reasonable degree of certainty is indicating the exact opposite.
I would encourage you to read what BF linked to. I did and they are some great articles.
