This sounds almost like the premise of the sci-fi novel Avogadro Corporation: The Singularity Is Closer Than It Appears. Avogadro Corporation was ironically modeled after Google, and in the story they develop a system using recommendation algorithms to automatically suggest improvements to one's emails so that they produce favorable responses from recipients. What happens is that one of the programmers modifies the system to give it an overarching goal, gives it the privileges to write and send it's own emails as any Avogadro Mail user (think any Gmail user), and it begins to socially engineer people, allowing it to escape into the wild, take over whole governments, etc.
This Google project sounds eerily familiar. Better watch out, this could spell the end of us all.
