Apple's new 'Liquid Glass' aesthetic for iOS 26 and MacOS 26 is being compared to Windows Vista's 'Aero' style from the late 2000s.
Design trends in tech industry tend to repeat every 10 to 20 years, with elements like transparency and frosted glass making a comeback.
Apple claims Liquid Glass combines the optical qualities of glass with a unique fluidity, reminiscent of the design choices made by Microsoft with Windows Aero 18 years ago.
The cycle of design trends continues with Apple's focus on round elements, which may shift back to rectangular shapes in the future, showcasing the cyclical nature of interface design.
