There's nothing harder than explaining a delusional idea - while still accepting that it's true.
Most individuals in this society take "consciousness" as some, often unique, mix of subjectivity, meta-cognition and other stuffs. It's also commonly taken as a quality characterizing humanness despite no agreement on what it is.
Thus I'd say "the hard problem of consciousness" is exactly the sort of problem science has learned to discard. It's hard like the problem of explaining astronomy in terms of astrology, the hard problem of reworking astronomy in terms of earth-centered coordinates and any science that attempts to carry-on without clarifying terms.
