  Fuchs and Peres (2000) claimed that standard Quantum Mechanics needs no
interpretation. In this essay, I show the flaws of the arguments presented in
support to this thesis. Specifically, it will be claimed that the authors
conflate QM with Quantum Bayesianism (QBism) - the most prominent subjective
formulation of quantum theory; thus, they endorse a specific interpretation of
the quantum formalism. Secondly, I will explain the main reasons for which
QBism should not be considered a physical theory, being it concerned
exclusively with agents' beliefs and silent about the physics of the quantum
regime. Consequently, the solutions to the quantum puzzles provided by this
approach cannot be satisfactory from a physical perspective. In the third
place, I evaluate Fuchs and Peres arguments contra the non-standard
interpretations of QM, showing again the fragility of their claims. Finally, it
will be stressed the importance of the interpretational work in the context of
quantum theory.
