Exceptions are exceptionally good at error handling - they always do the correct default (bubbling up if not handled, bringing a stacktrace with them, and by default they auto-unwrap the correct return value, not making the actual business logic hard to decipher), plus they make error handling possible on as wide scope as needed (try block vs a single return value).
I absolutely fail to see how a “random” C program would fair better, I’m sure the errno state is not checked at every line, as it is a trivial human error to leave that out. You can’t forget exceptions, which is how it should be!
If anything, that java/python text editor will catch every exception at the top level, save the file and exit with an error message and it will be the C program that either randomly crashes, or ignores some exceptional state.
