What's wrong with exceptions?
Exceptions opt out of the type system. The problem with them is the same problem as null. Here's a video of the creator of null explaining: https://www.infoq.com/presentations/Null-References-The-Billion-Dollar-Mistake-Tony-Hoare/
Null and errors are just values at the end of the day, and should be treated as such. Doing so means your code is far easier to reason about.
Rust takes this approach and is one of the many reasons people love it so much.
What @[email protected] said, but also they kind of have the same problem as goto. The control flow becomes very complicated and you can jump from one place in the code to another extremely far away.
Spooky action at a distance, basically.
Because exceptions are old and the new (recycled) kids are much more fun to play with? Or people yearn to implement the low level switch-case pattern error matching mechanism all over again, which try-catch-exceptions were solving.
I think there is no moving on from a paradigm as long as it has a function.
