So many YC folks are forking VSCode for various reasons that mostly revolve around "can't monetize extensions, want to own the platform". I don't think any of them will be successful, IMO. You want to be an extension because getting software approved is _hard_ at bigcos, it's much easier to trojan horse on an existing tool.
I think Cursor is already looking successful. Most VS Code people I know (including myself) have switched over. I love the idea of Haystack (I was a fan of Light Table back in the day) but if I have to pick between a better UI and an assistant who perform most simple code transforms by English language request, saving hour(s) per day, I’m picking the assistant.
I am curious what features you like about Cursor the most? For me it's the CMD/CTRL+K -- I've had mixed experiences with the chat window and Composer.
