There is no cultural backlash against expertise. That's a comfortable fantasy that a handful of self-proclaimed "experts" who have been consistently wrong are telling themselves, mostly people who attempt to predict the future but are not self-aware enough to understand their own biases.

I have yet to encounter any obvious or recent drop in regard for doctors, geologists, chemical engineers or indeed software developers, probably because none of those job categories make money by attempting to influence government policy via dubious predictions about the future.
