That's a cool analysis. What you're missing is the incredible backlash against Alan Dye.Apple is worth four trillion dollars, their entire philosophy that they have bet the next decade of their user interface on both wasn’t decided on by one guy, and certainly won’t be abandoned because said one guy jumped ship.
There will definitely be refinements, but anyone expecting them to completely abandon liquid Glass I’m afraid is going to end up having a rude awakening come OS ‘27.
The last time Apple’s head of UI was replaced was 2015. The OS released in 2016 looked almost identical to the ones released in 2015, 2014 and 2013.
If you’re looking for the next UI after liquid Glass, come back in the mid 2030s, maybe even the early 2040s. Aqua in one form or another was around for 13 years and the flat design was around for 12, obviously with variations, improvements, and optimizations along the way.
Very senior people at Apple read Daring Fireball, for example, and they will have seen the vitriolic posts from Gruber about Dye. I don't think I've ever seen Gruber attack an Apple employee in such a way.
People at Apple will have clicked through to the Twitter storm celebrating Dye's removal from the company.
So, I just don't think Liquid Glass is like "the usual" UX/UI revolutions at Apple, such as the one introduced by Ive a decade ago. Well, that's my two cents, anyway.
That said, I also don't expect it to disappear in a puff of smoke. But I do expect it to be "refined" significantly in the 2027 releases of the OSes. After all, Liquid Glass isn't a fundamentally bad idea. It's quite cool. It's just implemented in the most awful, slapdash way. Apple has already "refined" it a few times in the current OS releases by giving people control over its implementation.
