Naval Ravikant's tweet, "UI is pre-AI," sparked widespread debate in the design community, prompting questions about the future role of user interfaces in an AI-driven world. Some argue that AI will render traditional UI obsolete, especially in applications that prioritize functionality over design, like social media and e-commerce platforms. These products are increasingly driven by algorithms that understand user behavior rather than relying on aesthetically pleasing interfaces. In these cases, UI becomes secondary, with AI taking the lead in task management and user engagement. Conversely, there are tools where the interface is central to the user experience. Applications like Linear and Basecamp excel because of their thoughtful design and user-centered philosophy. For these platforms, UI isn't a relic; it's an essential part of their identity. The article suggests that as AI evolves, UI will polarize. On one end, we’ll see invisible interfaces that anticipate user needs, while on the other, high-craft designs that stand out as intentional choices. Designers will need to adapt, focusing on creating systems that not only look good but also behave intelligently, balancing automation with user control. This shift emphasizes that design is not disappearing; it’s transforming into a more complex role that incorporates AI behavior and user intent.
