I am having to make enhancements to a Ruby codebase where I barely know the language and the code base is completely foreign. So I tried using Cursor to provide AI autocompletion, suggests etc. It's definitely useful for this use case and so I can see the appeal for junior developers.

For my other code bases I find that the amount of time it saves is definitely nice but only barely worth paying another SaaS subscription for.

And so I'm happy to just wait for Jetbrains and Microsoft to roll this into the existing products for free.
