To be a bit more specific as to how _decoherence_ solves this, one way to see it is that classicality (i.e. observables having specific values) is an emergent property in the limit of near-infinite degrees of freedom in the same way that e.g. thermodynamic properties (temperature etc.) are emergent properties of…</p><p><a href="https://hackerpaper.kaipfister.de/p/1508.04101/">Paper and discussion history</a>.
