When I first saw Liquid Glass I had just gotten my first iPhone and was in that flush of attraction and thought “that looks pretty good” but there has been such an outpouring of scorn for it that I’m pretty shocked.
I think there was a time, long ago, that I justifiably believed that some of Apple's design was forward thinking. But, I think they are now more like WhatsApp, who apparently have a unit that is charged with ensuring that the UI does not change for fear of unsettling users.
I think this translates to - 'Apple has to play it safe as it is too big a company to make risky changes'. Ie, it can no longer do revolutionary things for fear of a collapse in faith of the consumer masses rather than the avidly convinced first adapters.
Imagine picking up a drill and it updates and now the trigger is somewhere new. And they've taken away the sped settings in the interest of simplicity?
