Apple's introduction of Liquid Glass at WWDC 2025 represents far more than a visual refresh. It's a calculated strategic repositioning that reveals how the company thinks about the next decade of human-computer interaction. While the design community debates readability and the tech press focuses on the absence of major AI announcements, Apple is quietly executing a playbook that should feel familiar to anyone who remembers the iPhone's introduction: prepare users for a paradigm shift by making the transition feel inevitable.
The Strategic Pattern
This isn't Apple's first rodeo with controversial design changes. The move from skeuomorphic design in iOS 6 to the stark minimalism of iOS 7 sparked similar debates about usability and aesthetic merit. Critics lambasted the "too thin" fonts and complained about reduced affordances (the visual cues that tell users what they can interact with). Yet within two years, the entire industry had adopted flat design principles, from Google's Material Design to Microsoft's Metro language.
The pattern is instructive: Apple doesn't just change design for aesthetic reasons. Each major visual overhaul has preceded a fundamental shift in how we interact with technology. Skeuomorphic design made sense when touchscreens were new and users needed familiar metaphors (buttons that looked like physical buttons, bookshelves that looked like real shelves). Flat design emerged when users had internalized touch interactions and no longer needed heavy visual scaffolding.
Now, with Liquid Glass, Apple is preparing users for a world where the screen itself becomes less relevant.
The Vision Pro Connection
The timing isn't coincidental. Apple explicitly credits visionOS as the inspiration for Liquid Glass, and for good reason. In augmented reality, interface elements must coexist with the physical world. They can't be opaque rectangles that block your view. They need to be translucent, layered, and contextually aware. As Alan Dye noted during the visionOS introduction, "every element was crafted to have a sense of physicality: they have dimension, respond dynamically to light, and cast shadows."
This isn't just about making interfaces prettier. In AR, visual affordances work differently. A button that casts realistic shadows and responds to virtual lighting feels more "real" when floating in your living room than a flat, colored rectangle. The glass metaphor makes intuitive sense when you're literally looking through a device at the world around you.
By introducing these concepts on traditional screens first, Apple is doing what it does best: making the unfamiliar feel familiar. When users eventually put on AR glasses, the interface paradigms won't feel foreign. The translucent panels, the layered depth, the environmental responsiveness will all feel like a natural extension of what they already know from their iPhone.
