Secondly, it was just one example that came to me from comparing this the other day. You could compile a long list of examples where Cursor gives better completions than Zed does.
I know that days of yak-shaving with LSP and emacs only gets me to a janky imitation of Visual Studio/XCode semantic search on my C++ work codebase. "Fuck it, let an LLM auto-complete based on vibes" has some appeal when you just get sick of trying to arm-wrestle clangd into ... whatever XCode or Visual Studio are doing to have functional semantic search across the project.
Although I have to say LLMs were a disaster at vibe-auto-completing in VSCode. So I mostly stick with semantic search in the IDE and editing in emacs like I always have.
