Taking a century or more to construct anything makes that thing larger than life. There's a certain sublime quality in such efforts, whether they're explicitly dedicated to a god/pantheon but also if they are "just" earthly like the White House (technically took 178 years to construct from start to finish).
Maybe if the project served a greater purpose and couldn't possibly be built in a shorter time, then it would mean more. But a cathedral? What's wrong with a modest church or two?
But building something extravagantly big has a signaling value all of its own: "see the glory of <whatever it is we constructed this for> and how much resources they command". You don't build a cathedral because it's more practical than a normal church for holding services and stuff, you build a cathedral to express the power of your religion and impress it on others.
Intentionality is a big theme in math research (so i've heard), where solving "useful" problems isn't the ideal goal. The goal is to solve interesting problems, which might seem useless, but along the way achieve results with much wider implications that would have been impossible to discover directly. Or, how inventions like toothpaste came from space travel research.
(rhetorically) Does an indirect result "justify" a longer, slower project? Is speed an inherent property of the problem, or is it only knowable once it's complete? Or both, in the cases of misused funds?
