Proto-nanites are here!
Yeah, but we didn't really design those, and we're not that great at asking them to perform tasks for us. This particular molecular machine isn't particularly useful, no - it's a single-application "device," which only works at profoundly low temperatures - but it's a step toward widespread deployment of nano-machines, and was worth bringing attention to, even if some other organism got there first.
Not to mention the fact that the power source was a macro-structure.
How many clowns can you fit in it?
As one of my friends pointed out, the guy who designed the nano-spanner must be the unsung hero of the operation!
