The Liquid Glass look comes largely from VisionOS, which shipped with a particular constraint: it had to layer digital information over your physical world, without occluding that physical world. Most of Apple’s devices have a lot of features in common, and it makes sense to bring them all more closely together. You really can’t look at Liquid Glass without thinking of Windows Aero, the similarly glassy and translucent design language that shipped with… Windows Vista. But for all the epic language of the unveiling, I don’t see much in Liquid Glass that will matter. Liquid Glass is the lowest common denominator, done about as well as you could.
