I guess it kind of depends on how you mean it, but I think there are many worse things... I've used software where actions that should be a single step are two or three steps (like a "click OK and now confirm that you clicked OK" for an inconsequential step out). I've played games with intentionally difficult UI, like QWOP. There are a few Windows computers at my work which are a bit older and when you go to open a program, nothing apparently happens, so you instinctively click again, and again nothing happens, so you either click again or wait a while, and then finally your web browser (or whatever) opens, but you get several windows open since you clicked it a few times, and this happens every time, just due to the way the UI delay happens. Also, there are experimental designs like https://userinyerface.com/ https://userinyerface.com/ which illustrate brutally terrible UX. So, in my experience, the Dwarf Fortress UX is definitely complicated and isn't easily discoverable, but at least it does what it's supposed to. It doesn't infuriate me the way that some things (especially truly poorly designed things) do. This is why I claim it's far from the worst.
