Well yes, kind of, and in conclusion no. Certainly the mythical golden past is a component of populism, and can be seen in Mussolini wanting continuity with Romans, and Putin weaving his own myths about Russian history - I forget the details, but it entails more territory for Russia because historicist destiny - and "Little Englanders" (the look-backward, xenophobic kind, not the original ones who were just isolationists). On the other hand, Musk kind of likes looking toward the future. So this thing about a mythologized past is at most a tendancy, and a way of stirring up a sense of injustice, while your non-authoritarians don't have the monopoly on looking to the future. In fact I don't see that these are even polar opposites, I think authoritarian progressives would make sense as a concept, and we may be seeing a bunch of them rise to power.
