I've been a paying customer for Jetbrains IDE for years.
After trying Cursor, I'd say if I were Jetbrains devs I'd be very worried. It's a true paradiam shift. It feels like Jetbrains' competitve edge over other editors/IDEs mostly vanished overnight.
Of course Jetbrains has its own AI-based solution and I'm sure they'll add more. But I think what Jetbrains excels -- the understanding of semantics -- is no longer that important for an IDE.
Why would they be? Cursor took an existing editor and added some AI features on top of it. Features that are enabled by a third party API with some good prompts, something easily replicable by any editor company. Current LLMs are a commodity.
