Yeah, self-replicating machines could be cool. Not necessarily dangerous, too, depending on exactly how robust and good at using a variety of materials they are. If we just make a slightly different version of delicate seafloor bacteria that's not very scary.

That being said, you could 3D print most of a normal electric motor. I'd have to actually read the research to know how this triboelectric design compares.
