That would be a bit creepy though. Imagine a factory of chinese workers, all sewing and this this silent rolling monster drifts slowly by, and they all stiffen in fear and work extra hard...
At this point, it's probably trivial to make it go past everybody every few days just to scare people, right?
That's the logical result of widespread adoption of this, isn't it? Similar to (most) security CCTV right now.
Either that, or elaborate "moon-landing" setups to trick the remote factory (or weapons) inspectors.
