The gesture controls of the iPhone X were stunning back in the day, and today’s macOS is just that bad. This brings to mind the departure of the industrial designer of the iPhone Air. Then I think of the era of Jobs + Jony Ive, when the industrial design department and the human-computer interaction department of the iPhone were one department. After Jobs left, Jony Ive independently delivered the Touchbar MacBook, which (at least on the surface) seemed to be a product of close collaboration between industrial design and human-computer interaction. But at the same time, lacking Jobs' checks and balances, he also left Apple due to overly radical designs like the trash can Mac Pro and the butterfly keyboard. After Ive's departure, Apple split his two deputies, Evans Hankey and Alan Dye, into two parts: industrial design — Evans Hankey, human-computer interaction — Alan Dye. Interestingly, they both report to COO Jeff Williams, yes, to the COO. This combination had a honeymoon period, which was the output of the iPhone X — hardware with a full screen + leading interaction design. Even up to this generation of the iPhone 17, they still haven't stepped out of this framework. However, everyone can feel the growing disconnect, such as the notch on macOS, which obscures the menu bar, with no software-level handling. Yes, when you split departments, the philosophy of integrated hardware and software evaluation is also split. It's not that without Jobs, Apple can't produce good things, but it can be confirmed that Apple's good products are becoming fewer and fewer. This reminds me of the various inexplicable demos from Apple Intelligence at WWDC in the past two years, and the legendary Gemoji advertisement, Apple is truly losing its taste. The departure of some people won't immediately cause problems, and some decisions don't always show effects right away. Recently, I often think, if Jobs were still around, what would Apple’s Liquid Glass be like? I believe there wouldn't be any bugs in Glass rendering because Jobs would be roaring at the engineering team; I believe there wouldn't be the strange view of Only Text on macOS 26 Finder because Jobs always cared about all the details; I believe there wouldn't be the current inexplicable wallpaper designs, strange tinted icons, nor would there be clear/tinted switches. Upon reflection, there wouldn't be any cleverly inexplicable Liquid Glass in the future, and the iPhone might have long been the iPhone Classic. Finally, in 2023, Evans Hankey leaves, and in 2025, Alan Dye departs. The legacy of Jobs + Ive has basically been wiped clean. Steve Jobs's Apple has long been Tim Cook’s Apple. Perhaps this no longer matters, because smartphones are no longer the most important thing in this era.
