Having your business code riddled with error handling code is just bad design, and will inevitably result in not properly handling certain cases simply because the developer would prefer to write the actual business logic and can’t always stop doing that. Exceptions (especially checked ones) allow for as fine or crude-grade error handling as needed. Don’t get me wrong, Java’s checked exceptions are not without problems, but compared to Go almost everything is better in this regard.
