Google Hangouts wasn't small. Google+ was big and supposedly "the future" and is the canonical example of a huge misallocation of resources.

Google will have no problem discontinuing Google "AI" if they finally notice that people want a computer to shut up rather than talk at them.

Wait until Apple's ChromeBook competitor shows up to eat their lunch just like switching to another proprietary stack with no dev ecosystem will die out. Sure they'll go after big ticket accounts, also take a guess at what else gets sanctioned next.
