Skynet I mean Google spreads its reach even further... 
So the Google search results have been gradually changing away from the 10 listed results that users were searching for, to more and more Google owned results, such a maps listings, Google Plus and adwords.
Semantic search has given us the carousel and knowledge panels hoovering up site content and repackaging it so a visitor never needs to leave Google. Now the obvious next stage, Google will display your content, can already display products and now people will complete the purchase on Google. Who needs a website 
Now to get that buy it now button will require you to buy it now 
So as long as you play the game, conform to the Google rules, pay for the privilege, then it should work very well.
Does seem to go against what Google was all about back in the beginning? Guess that's progress $$$...
