Go's error handling is honestly the best I've ever used. No errors go unhandled. Period. get an error? Return it or deal with it. Makes much more sense than exceptions suddenly breaking the behaviour of the language.
There are many situations in which you want errors to go unhandled and bubbled up to some common error handling logic.
Exceptions IMHO are vital. They standardise error handling behaviour across your application and provide flexibility in when, where, and how you handle groups of errors.
func foo() error { return errors.New("whoa!") }
func bar() {
_ := foo()
// onward!
} try {
foo()
catch {}
