Spotted: Google Search Results Feedback Pop-up

First time seeing this pop-up asking for feedback on the results: (I clicked ‘somewhat satisfied’ and Google thanked me for my feedback – forgot to screenshot, sorry!)

Does this mean Google is going to start crowd-sourcing their results? Are they waving the white flag and admitting they can’t get rid of spam and asking for every user’s opinion? Seems like this is a can of worms they should be wary of opening.
