Well, they don't look like paper, but as in all things with the new economy, it's more about symbolism than reality.
More intriguing than the "paper" aspect was that they're the simplest things which can fly. They're unpowered. There's just enough resolution in the photos to see the airplane uses 2 stock Plantraco actuators. The monocopter doesn't seem to have control.
Obviously, they're not autonomous. They could be useful for plotting temperature & humidity vs. altitude. They couldn't plot air pressure vs. altitude because air pressure is needed to determine altitude. There's a chance of using them to plot radio reception for a different radio than the one used for flying. Cameras aren't quite small enough to fit on there.
