That doesn't sound like a gift to me. Unless you meant they are so painful as an abstraction that they gifted us with promises and then async/await.

Almost everyone here has worked with callbacks and you'll be hard-pressed to find people that felt like they improved the code base.

Just tiny changes to the logic, like an if-statement with branching async behavior, would cause disproportionally large changes in the callback structure, pretty much touching every line/indentation.

The rest of your post is really negative and judgmental. Not sure why you felt it was necessary.
