Exactly. When I was young, most quantum physicists did not believe we could get an interference pattern with single particles, like de Borglie thought initially that all superposition where microscopic. They were refuted on this, and the mystery of QM is that it works apparently at all scales. The decoherence theory explains only why we cannot see them directly.
