On the positive side of things, the notion that performance is multivarious and means different things to different contexts has really sunk in with the general tech demographic and we don't see much of the "one big number that sums it all" type of stuff. Think the GHz race or FPS measuring contests.

Both with the GHz race and FPS measuring contests, we've gotten to the point where there's substantially diminishing returns - GHz has stopped growing in the same way, and reaching the limits of human perception with FPS is generally readily achievable, and so it loses interest as a contest.
I suspect your broader point stands - certainly "performance is multivarious and means different things in different contexts" has sunk in for me. But I suspect the actual difficulty of reasoning about performance deters most people from doing it beyond big O notation. The fact that I'm aware that performance is complicated doesn't drive me to understand the complexity, I mostly just say "good enough" and move on.
