Think of how much time you'd have to spend writing trivial tests instead if you didn't have an automated system to detect basic mistakes like typos and type confusion!
I guess you can complain that Typescript forces you to spend time making sure your code meets a minimal bar of correctness...
Library developers in particular should see type complexity as a warning that something isn’t great in the design. This seems largely an issue for libraries migrating to TS which isn’t a surprise.
