At the very least, now it seems Google is making all their applications fairly standardized in their UI/UX. I think that's Material Design at work, but I'm far from a UI/UX person.
Are you serious? Every Operating System manufacturer these days "standardizes" their UI across their whole offering every few years (Microsoft, Google, Ubuntu and Apple are all on board). Just a moment ago, Holographic Design was the thing on Android. Let me guarantee you that Material Design will be, too, a thing of the past in a couple of years. What the designers don't seem to realise is that this is frustrating to the users.
