It's worth actually trying Cursor, because it is a valuable step change over previous products and you might find it's better in some ways than your custom setup. The processes they use for creating the context seems to be really good. And their autocomplete is far better than Copilot's in ways that could provide inspiration.

That said, you're right that it's not as overwhelmingly revolutionary as the internet would lead you to believe. It's a step change over Copilot.
