I always think of "golden ages" as arising naturally from a random distribution of "big breakthroughs" and similar. It's not unlikely that you'd get some clumps of many breakthroughs followed by time with very few breakthroughs. And we call these clumps "golden ages." And of course, the fact that they're not independent events, but that one breakthrough might precipitate another, just reinforces this.

So I don't think "golden ages" are going away any time soon.
