I've tried switching from JetBrains IDEs just a few days ago. The speed and memory footprint are very impressive. I ended up badly missing refactorings and some other features and configuring a debugging session looked like something that needs more time than I had on my hands. So went back for now. I hope they add more IDE features eventually. There's not much a pure text editor can offer over Emacs after all. But this announcement sounds like they are prioritizing agents integration - the same thing that seemingly made JetBrains drop the ball on their core advantages.

JetBrains should really start investing into porting to Rust/C++ over their bootleg Java.

Was in the same boat. I ended up not using Zed because it had a bunch of minor quirks that annoyed me but I moved to vscode. I primarily write Typescript and C# these days. I was a JetBrains fanboy for years and it feels way too bloated now, stuff notoriously hangs or takes too long on my M3 Pro. I also love Claude Code integration with vscode just a bit too much to give it up for CLI.
