> we can't even build self assembling macroscopic machines

TRL-1 tends to imply such statements :)

… although, is that actually true? For macroscopic, I mean? Given factories exist and robot arms are part of them, are you sure nobody has used a robot arm to assemble an identical robot arm from a pile of robot arm parts? I've not heard of anyone actually doing so, but are you sure that's never been done?
