I'm not going to bang this drum too much, because it's been done to death for well over a decade, but lines-of-business supported by CRUD apps are rarely simple from an engineering perspective. Much of that engineering is in the decisions made outside the codebase, or spread across multiple codebases. If you're looking for the one obviously brilliant line of code to tip your fedora to while sipping your snifter of wine, you're not gonna find it. In fact, "clever" code like that is rightfully and instantly rejected as cowboy code.
By your reasoning, civil engineering isn't "real" engineering like aerospace cuz they don't build things that go really really fast and shoot out fire and stuff. Also, there's like too many responsibilities delegated out. Like, man, I only wanna talk to the guys who put the rockets on the thing. Everyone else are just overpaid slackers that smooth talked their way! They're gonna get replaced by AI! Mark my words!
