I still disagree. Quantum does not imply nanoscale - we are building bigger and bigger systems that exhibit inherently quantum behavior (for instance superconducting cavities used in quantum computing research are centimeter scale). Moreover, the jump is not necessarily in a spatial variable - it can be a very big jump in energy levels for instance, which is the case with laser emissions. Sure, a (big or small) discrete jump does not necessarily imply a jump to something better, but that has little to do with my complaint about the meme that "quantum implies small".
