I would love to be able to have a conversation with the people who decided Liquid Glass was a good idea. The first question would be:

Given all other truly useful things you could implement as well as bug fixes, why did you think that investing time and money on Liquid Glass would deliver useful value to users?

I wonder how much time and money they wasted on something that nobody wanted, cared for, needed or solved any real problem?

My theory is they made Liquid Glass for the Watch first, where (IMHO) it's actually pretty great, and assumed it would translate well to iOS and macOS, which in retrospect it did not.
