Cursor ditches VS Code, but not everyone is happy...

📚 Main Topics

Cursor EvolutionOverview of Cursor's development from version 1.0 to 3.0.
Composer 2 ModelIntroduction of the new in-house coding model and its capabilities.
Interface ChangesTransition from a VS Code fork to a completely rewritten interface in Rust.
Real-World ApplicationDemonstration of using Cursor 3.0 in a project.
SponsorshipIntroduction of Blacksmith as a tool for GitHub actions.

✨ Key Takeaways

Cursor 3.0This version shifts the focus from writing code to managing AI agents, likening the user role to that of an air traffic controller.
Composer 2Claimed to outperform existing models like Claude Opus 4.6, but later revealed to be based on the Kimmy K2 model, leading to transparency concerns.
Performance ImprovementsThe new interface is designed for better RAM usage and allows for seamless management of multiple coding agents.
Real-World Project ExampleThe video showcases the rapid development of a prototype using a swarm of agents, demonstrating the efficiency of the new system.
BlacksmithA tool that enhances GitHub actions, promising faster performance and cost savings.

🧠 Lessons Learned

Shift in Development ParadigmsThe move towards AI-driven coding suggests a future where traditional coding may become less central, emphasizing the need for developers to adapt to new roles.
Transparency in AI DevelopmentThe importance of clear communication regarding the origins and capabilities of AI models to maintain trust within the developer community.
Efficiency through AutomationLeveraging AI agents can significantly reduce development time, allowing for multitasking and parallel project management.
Critical Evaluation of ToolsAs new tools emerge, developers should critically assess their claims and performance to ensure they meet project needs effectively.

Transcript excerpt

0:00 Two years ago, Cursor 1.0 was released as a VS Code fork that helped you autocomplete your code with AI, like an airline co-pilot. Then six months ago, a cursor 2.0 was released, but with an upgraded chat view that could take control of your terminal to build entire features, like an airline captain. But then, just a few days ago, a cursor released version 3.0. And this version doesn't even want you writing code anymore. Instead, it wants you to be more like an air traffic controller running swarms of AI agents across multiple repos, machines, and even the

0:31 cloud at the same time. On top of that, Cursor just released their new composer 2 model, which was allegedly trained in-house and is more intelligent than Claude Opus 4.6. That is, if we are to trust these trust me, bro benchmarks. But what's even more crazy is that cursor is not even a VS Code fork anymore and has been completely rewritten from scratch with Rust. That's great news for your RAM, but not everybody is vibing with the new direction of cursor. And in today's video, we'll break down its controversial new features. It is April 6, 2026, and you're watching the code
