I saw career advice recommending against front-end development — "you're dependent on backend APIs — they're always late, putting front-end dev under severe pressure." Sad, but it's a story I hear often. The problem is that framework-based API development is slow and complex.
I also hear snide remarks that "if you don't like the answer from UI #1, try UI #2." It's because the logic is often not shared in the server but replicated on UI controllers.
