I've been talking to Nathan and think he has a good handle on the issues. One of the biggest mistakes in xi was an over-reliance on async and a loose coupling between the main logic and the UI surface. Zed isn't making those mistakes. I'm eager to see what the come up with and look forward to friendly competition in the open source Rust UI space when they release their toolkit.
Is Zed related to Xi in history or as inspiration? Why are you confident that Zed will be able to overcome the issues that blocked Xi's advancement?
