Eh… Architecture can be art…

But first and foremost, architecture should be aiming to make comfortable, convenient, and useful places for people to live or do things.

Art is a nice bonus (if budget and time constraints allow), but it’s perfectly valid to build ugly utilitarian buildings if those buildings accomplish what you need them to do.

Which, unlike what the meme implies, is something the ancient Greeks knew. Yeah, they had some beautiful architecture, but they also had a lot that’s purely functional.
