A translator who translates not words but the very structure of a conversation runs into trouble when the chat moves beyond a quiet room. In a familiar simulation on a spatial lattice, everything follows a strict script. But the moment the interlocutors find themselves in a noisy square, where sound is distorted by echoes and the crowd keeps changing direction, the script falls apart.

An orchestra without a conductor, where musicians hear each other through a shared wall. That's roughly how the new type of laser works: a few atoms (emitters) sit along a waveguide — a thin track for light on a chip. Light from each atom runs along this track and affects its neighbors.
