I was making a joke, but if you'd like me to be serious, I do know about RepRap, and I have to say: the premise that we can make self-replicating devices (or device families) that not only reproduce themselves, but acquire the resources for their reproduction in an efficient way, seems far-fetched to me. That is what this article is about: we assume that evolution has made refinements on reproductive processes that should be clues for people trying to improve self-replication in machines. Unfortunately, even biological processes, honed by millenia of natural selection, are pretty wasteful, because most of them have never had to adapt to Earth's very finitude.
