It's just interesting seeing someone promote the precise opposite of the now ever so popular Material Design thought of basically using animations everywhere to convey motion, meaning, and hierarchy.
Everything can be overused. Microsoft pretty much invented the "flat" movement that has been happening but they're also guilty of making things so flat and undefined that you don't even know what to click on! The iPhone uses animation as filler to hide slow app loading in the first gen but it isn't necessary anymore. Even skeuomorphism is ok when it conveys meaning but most uses are garish effects that provide zero benefit.
Animations that are merely cool looking might be fun for the first dozen times but then it gets old.
So I understand not wanting to watch some stupid animation over and over instead of just getting to the point. But some animations are helpful for seeing when things change.
