I would agree. Today it is called story, or analogy or metaphor etc
If the story is told as a truth in order to deceive the recipient it will be called a lie, Propaganda, spin, BS, or some other.
There are many ways to skin a cat now. If anything our mythos has become more sophisticated.
As you continue to catch up, you'll find I agree as well.
So allow me to refine my statement ftr: we have forgotten that
religion is an expression of
mythos.
I do disagree that it's become more sophisticated, however. Take movies: while some are mythic indeed, their popularity is dwarfed by thoughtless explosions and FX-travaganzas.
The most profound AND successful movies I can think of off the top of my head:
LotR: Tolkein was brilliant, but how many folk appreciated more than pretty elves and spectacular battles?
The Star Wars franchise, which while it follows mythic archetypes, is ultimately quite shallow
Avatar, which was more political than philosophical and still not incredibly thought-provoking.
Last and least, dishonorable mention to the Matrix series. UGH.
