Is try..catch really useful?

I ended up making an account for this one. Exceptions are a section in one of my favourite blog entries:

Their argument is that Exceptions are GOTOs in disguise and point to the use of sum types.

I have found this to be good advice when using Java 8+. Composing Optional<?>, Either<?, Exception>, or CompletableFuture<?> has provided sufficient tooling for handling failure scenarios.

I also find that Exceptions slow down my reasoning about code, because they are side effects - see functional programming.

The Try pattern is good but if you are using a whole bunch of libraries/existing code that doesn't use it already it's just going to be confusing to introduce it.
