This is likely going to look really cool and feel even better on iOS and iPadOS. The phones haven't changed visually (hardware or software) a ton in a decade because, frankly, they are a really mature and solid product. There's a reason not many iPhone 15 users upgraded to 16. With Liquid Glass, for once in a long while iPhone users will look down and instantly see drastic change. Remember iOS 7? That took a long time to iron out all the "oof!" as well. But it slowly did improve.
On MacOS, though, I really do worry it's going to take several iterations before things make a lot of sense. God forbid this new UI layer hurts performance, too, on these exceptionally fast machines.
Good news is things are still in beta. Some ideas can always be walked back.
Organizationally, Apple have definitely stuffed the Mac. Catalyst was a mistake and with hindsight they should have just made SwiftUI more capable, earlier. But now they’re focusing on building Android apps with it too?! To say nothing of locker service etc.
