What is Open VSX and why AWS backing?

Open VSX is an open extension registry for VS Code forks, free from Microsoft's restrictions. AWS's investment funds European AWS-hosted infra, boosting reliability for AI editors like Cursor and Kiro.

Why VS Code declining in Rust survey?

Dropped to 51.6% from 61.7% as devs flock to faster, AI-native rivals like Zed (18.6%). Microsoft's AI features feel bloated to speed-focused Rustaceans.

Will Open VSX replace VS Code marketplace?

Not fully soon — fewer extensions — but AI and sponsorships (AWS, Cursor) position it as the neutral hub for agent-driven dev, potentially matching scale by 2028.
