>"Yet nature is not scale-invariant. E.g., you can't take a carbon atom and scale it by a factor of 10 and make it behave in the same way as the original atom." That's a major caveat, although I think in the end it just makes things more interesting. "There's plenty of room at the bottom" as Feynman said. Technologies like nanophotonics will allow us to have things like sold state LIDAR and perfect spatial tracking for virtual reality. Also to boost solar cell efficiency to ranges >50%, which has been impossible with the classical light modeling used up until now. Perhaps the reality is that all of these scales are linked fundamentally, but proving that would be quite a task.
