Remote is the killer app. I don't like VSCode but it is the only modern editor capable of a modern native-ish local UI while running acceptable-ish code indexing and intelligence on a remote server. As my company's monorepo grows, laptops increasingly choke on it. JetBrains Projector/Gateway are interesting prototypes but don't work reliably yet. It's not as bad as VNC, but it feels closer to VNC than to a genuine local native app with a client/server architecture.
