Google+ is a great example, because there was a very similar mindless push to integrate it into all of their products, by any means necessary. And then, when it fizzled, there was the inevitable engineering effort to rip it all out. I predict in a few years, when the AI fad has subsided, there will be a similar amount of engineering effort undertaken at all of these companies to pull out and sunset these expensive AI integrations...

Was it that one or Google Wave that was supposed to become the dominant form of communication within 5 years? I don't remember much about either one.
