In practice people catch runtime exceptions all the time so it's treated more as a recoverable error than a bug. Java let's you recover from runtime exceptions as easy as checked exceptions which blurs the distinction.

> And if you are only writing a prototype, declare that it throws Exception, or if you can't, a catch (IOException ex) { throw new UncheckedIOException(ex); } really isn't that bad.

The problem with that is when you go back to do proper error handling you can't easily find all those places where you did this. For instance in Rust, you can find those by searching for `unwrap`.
