While I intuitively feel “cultural drift” is a fruitful concept, it is unclear to me what it is, apart from a catch-all concept for all types of changes where one cannot immediately see “ok these cultural ideas & practices are obviously adaptive for the organism”.

The concept is inspired by the concept of “genetic drift”. And when evolutionary theorists use this concept, it seems to me that they often use it as a get-out-of-jail-free card. When they face some queer behavior in an animal or some queer type of antlers or whatever that does not seem to represent any evolutionary advantage, some theorists throw up their hands and say: “Well, what we observe can simply be the result of genetic drift”.

Which is true, it can be! Genetic drift is real. But it is also a lazy type of explanation. The fun part of evolutionary theory is to consider strange behaviors or strange body morphology as a puzzle (in the Kuhnian sense), and then to attempt to solve that puzzle by suggesting (and testing) hypotheses why whatever is observed, may actually be adaptive after all. (Example: Amotz Zahavi explaining gigantic antlers on some deer as the evolutionary outcome of a partly runaway signals arms race.)

Likewise, to jump too fast to the suggestion that an observed change in human culture is due to (random) cultural drift, rather than by changes in the environment that actually make the new cultural practice/behavior adaptive for the organism (in ways we yet have to find out), seems to me – well - a bit lazy perhaps….

…don’t get me wrong: there are good reasons to assume that cultural drift, as well as genetic drift, are real processes taking place in the world. But we should not jump to them as explanations of observed behavior before first considering less random-based alternative explanations.

For example, the dominance of “modernism” and later “post-modernism” in art and architecture is not due to cultural drift, but due to the Nazis losing the Second World War. Culturally, we are still living in the shadow of the outcome of that war. Nothing “random” there, once you factor in that the Nazis lost. If they had won, “Entartete Kunst” would highly likely still be a minority thing, and neo-imperial architecture a la Speer would be the order of the day.

Be that as it may. My main/theoretical point is that “cultural drift” is a bit vague as a concept. Further specification of what the concept signifies/what goes on according to it, is needed.

I don't see where you argue that modernism is *bad*. To call it "drift" suggests it is bad, and not a legitimate response to social problems.

As you say, modernism is motivated by disillusionment with prior ideals. By the timeline, these ideals that the early Modernists rebelled against were Victorian-era ideals. This would only be bad if those prior ideals were actually all good. Are you claiming that Victorian-era ideals were all good?
