I don't know that anybody ever cared. The barrier to entry re: running an IT infrastructure has fallen so far that gross incompetence still delivers a serviceable-enough product.
Eh, I wouldn't say it's fallen. There's just as much incompetence per capita as there ever was. I just think there are a lot more people working in the tech sector than ever before so it's more noticeable.
There are so many more tools to allow the incompetent to "deliver" a reasonable-enough result. There's a certain amount of "don't let perfect be the enemy of the good" in there, for sure, but like the grandparent poster, I've walked into many gigs where "long-standing problems" turn out to be easily fixed. Nobody with sufficient background knowledge and experience ever looked at them and they just festered.
That's a depressingly accurate portrayal of the situation.
