If I move off Cursor, it's def not going to be to another vs-code derivative.
Zed has it right - build it from the ground up, otherwise, MS is going to kneecap you at some point.
If you can't invest in yourself without making the same size investment in your competitor, you probably have no path to actually win out over that competitor.
Additionally, Zed is written in Rust and has robust hardware-accelerated rendering. This has a tangible feel that other editors do not. It feels just so smooth, unlike clunky heavyweight JetBrains products. And it feels solid and sturdy, unlike VS Code buffers, which feel like creaky webviews.
