If your coworkers are so bad, wouldn't you rather get a nice message in your console when they forget to handle an error? With callbacks, error handling is entirely on the honor system.

There may well be some situations where callbacks are tolerable, but any time you have to converse with an external synchronous resource like a filesystem, database or REST API, it's just painful. Making a new function (named or otherwise) for each line of code is not good style, in any language.
