  Quantum-mechanical interpretation-related implications of the theory of
unitary premeasurement [1] on complete measurement (objectification or collapse
included) are investigated in the present article with a view to give an
affirmative answer to the question in the title. It is argued that both Bohr's
and von Neumann's ideas lead to those of Everett. Hence, the latter can be, in
some sense, considered to be a continuation and elaboration of both former
approaches. The importance of the idea of relativeness in Everett's theory is
emphasized. To free the relative-state theory from its roots both of
classicalness and of subjective observation in the argument of this study, the
general or unfolded version of Everett's theory is sketched.
