Guest: Ryo Lu, Head of Design at Cursor
Introduction
In this engaging episode of Dive Club, host Ridd sits down with Ryo Lu, the Head of Design at Cursor, one of the most influential companies in the tech landscape. Ryo shares his journey from joining Cursor, the evolution of the product, and his visionary thoughts on the future of software design in an AI-driven world.
Joining Cursor and Early Experiences
Ryo begins by recounting his initial interactions with Cursor in August of the previous year, before the AI agent was introduced. He explains how Cursor's trajectory shifted from being a tool primarily for coders to a more versatile platform catering to a broader audience.
Ryo (00:36): "Instead of you're designing exactly how this piece of UI will look, you're actually designing a container."
Ryo emphasizes the transformational shift in design philosophy, moving from static UI elements to dynamic containers that adapt based on user needs.
Prototyping the Future Notion
Ryo narrates a pivotal moment when planning at Notion led him to experiment intensely with Cursor. Over three days, he built a comprehensive prototype of a "future Notion," leveraging Cursor's AI capabilities to rapidly iterate and visualize complex features without the traditional constraints of software development.
Ryo (04:30): "I built, like, a 3D globe view. But the idea is, like, in Notion, you know, we have, like, board table galleries, but you could have your own, like, custom views."
This prototype demonstrated the potential of AI-powered tools to democratize software creation, allowing individuals to bring intricate ideas to life without assembling large teams.
Simplifying Cursor's Concepts
Upon joining Cursor, Ryo identified that the product had multiple fragmented concepts, each with its own interface and key bindings. His primary achievement was unifying these disparate elements into a cohesive system centered around a single AI agent.
Ryo (06:00): "All of these things are the same thing. They're all agents. Then we merge all of them into one concept."
This unification significantly enhanced user experience, making Cursor more intuitive and accessible, which Ryo credits as a major factor in Cursor's rapid growth post-February.
Designing for a Diverse User Base
Ryo delves into the challenge of designing Cursor to cater to a wide spectrum of users, from seasoned developers to non-technical individuals. He explains the importance of creating flexible interfaces that adapt to individual preferences without imposing a one-size-fits-all solution.
Ryo (12:31): "Cursor might change how it feels depending on who you are."
He highlights the necessity of designing containers rather than fixed UIs, allowing Cursor to morph its interface based on the user's role and requirements.
The Future of Software Creation
Ryo shares his vision for the future of software development, where AI-driven agents play a pivotal role in facilitating seamless collaboration between humans and machines. He anticipates a shift from traditional coding to more strategic and conceptual interactions with AI.
Ryo (18:32): "In order for this to work, you need to solve some pretty hard, deep AI technical problems."
He discusses the technical and design challenges involved in managing multiple AI agents, ensuring they operate cohesively, and maintaining a high-level understanding of projects without overwhelming users.
Personal Design Process and Feedback Management
Ryo outlines his personal approach to design at Cursor, which involves continuous experimentation, dogfooding the product, and iterating based on comprehensive feedback from various channels.
Ryo (26:51): "I just look at everything on Twitter, in Slack, all the like user reports and feedback."
He emphasizes the importance of filtering feedback to focus on strategic directions rather than getting bogged down by individual suggestions, building intuition through accumulated insights.
Collaborative Design and Engineering
Ryo discusses the evolving dynamics between designers and engineers at Cursor. He advocates for a more integrated approach where designers are actively involved in the coding process, breaking down traditional silos and fostering a collaborative environment.
Ryo (48:00): "I made stuff myself. I designed the thing in my mind, I coded it, and then I became a designer."
This holistic involvement ensures that design decisions are deeply intertwined with technical implementation, leading to more cohesive and scalable solutions.
Personalization as a Core Design Principle
Throughout the conversation, Ryo underscores personalization as a fundamental goal. He envisions Cursor as a platform that can dynamically adjust its interface and functionalities based on individual user profiles, enhancing both usability and efficiency.
Ryo (39:56): "If you start from that, like, from that layer and you build a system around how to interact with like a. Any code base and solve a lot of like, hard AI software engineering problems so that the agent can make more complex software check its own errors, get better as you use it, then it's much easier to build upper layers."
Ryo believes that personalization will enable software to maintain its "soul" and craftsmanship while scaling to millions of users, ensuring that each user feels a personal connection with the tool.
Innovative Projects and Quick Prototyping
Ryo shares anecdotes about his personal projects, such as building mini operating systems and other experimental tools using Cursor. These projects are not only exercises in creativity but also serve as practical experiments to push the boundaries of what's possible with AI-assisted design.
Ryo (45:20): "One of the reasons I joined Cursor is I want the gap between have an idea and it becoming reality. Getting that closer to zero."
His ability to rapidly prototype and iterate exemplifies the power of AI tools in bridging the gap between conceptual ideas and tangible products.
Vision for Human-Computer Interaction (HCI)
In a thought-provoking closing, Ryo speculates on the future of HCI, where interfaces become extensions of human thought, potentially eliminating the need for traditional proxy devices.
Ryo (55:12): "The interface will just become, like, how you think, and I think it will just get closer to you."
He references advancements like Neuralink, envisioning a future where technology seamlessly integrates with human cognition, allowing for more natural and intuitive interactions.
Conclusion
The episode concludes with Ridd expressing deep appreciation for Ryo's insights and contributions to Cursor. Ryo's forward-thinking approach and dedication to simplifying and enhancing the user experience through AI-driven personalization underscore the transformative potential of modern design philosophies.
Ridd (56:43): "It's been really, really fun to see how you work, and I'm even more appreciative that you took this role than I was at the beginning of this."
Ryo reiterates his commitment to refining Cursor and shaping the future of software design, leaving listeners inspired by the possibilities that lie ahead.
