From your article:

  In the example Google showed us, a graduation photo came
  through. The suggested replies were along the lines of
  "Congratulations!" and "You look great!" Think for a moment about
  what it takes to do that. Google recognized it was a graduation
  photo and then went a step beyond just guessing what it was, it
  guessed at appropriate responses.

Umm. Its suggestions are no better than a simple like. It's less than greeting card sentiment. And it removes the need to even know what you're looking at. I'm not sure that's really a positive thing. Thread full of messages responding to pictures that the users never looked at. It's bad enough that for many people birthday and anniversary and holiday well-wishes are a simple "Happy Holidays" on someone's FB timeline or a text. Do we really need to automate sending those so that the sentiment is delivered but never actually shared?
