I think my conspiracy theory is more likely to be true:
>I've speculated for a long time that basically anything interesting Google says they're doing is essentially meant to be a jobs program to keep employees from leaving, PR for external stakeholders like investors, media, being attractive to potential employees, etc. They seem to have lots of formal ways to keep employees from leaving/close as well including investments off of Google's balance sheet (not GV or Google Capital) into ex-employee startups and just flat out paying people not to leave (which is the arrangement I'm guessing that Matt Cutts is under). It all seems very Microsoft of old.
