Cursor has absolutely changed the way I develop software. To be able to go from idea to running an application in hours or minutes is a game changer. Being able to integrate with several different models makes it easy to experiment. I do wish that they didn't force you to use their Pro service for the Composer experience, since it doesn't come with the same data governance guarantees as going direct to the model provider. But it's so good I can hardly complain...
Good user experience, genuinely increases productivity. Sometimes gets in the way, but it is not singular in this respect.
