Anything above a simple app and it becomes a tradeoff that needs to be carefully tuned so that you get the most out of it and it doesn't end up being a waste of time. For many use cases and domain combinations this is a net positive, but it's not yet consistent across everything.

From my experience it's better at some domains than others, and also better at certain kinds of app types. It's not nearly as universal as it's being made out to be.
