  The idea that decoherence in a unitary-only quantum theory suffices to
explain emergence of classical phenomena has been shown in the peer-reviewed
literature to be seriously flawed due to circularity. However, claims continue
to be made that this approach, also known as "Quantum Darwinism," is the
correct way to understand classical emergence. This Letter reviews the basic
problem and points out an additional logical flaw in the argument. It is
concluded that the "Quantum Darwinism" program fails.
