I know most people couldn’t care less about this, but those gimmicky animations probably consume more computing power than the entire Apollo project, which strikes me as unnecessary and wasteful. Given the choice, I’d much rather have a clean, efficient interface.
I tend to like Material Design in comparison. It’s clean, efficient, and usable. I just hope Google won’t try to "improve" it with annoying gimmicks and end up making things worse, like Apple did here.
