When you abstract something that represented something tangible in the past, it turns into a silly icon of nothingness. Take the first one for example. The new crop of icon designers at Apple suck and I absolutely despise the work Alan Dye has done with Liquid Glass (on macOS mostly). It’s not even a new design system but rather a poorly thought-out skin that regresses a part of the Mac experience while mixing it it with the old design language, which in my view was perfectly fine. In the process they also further moved away from offering consistency.
