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.
