From my personal interactions with Google's execs, with I completely agree that Google is sincere in this vision, and really is thinking big. But whether it's Google who builds this platform or someone else, or whether it's a tapestry woven collectively by many companies and projects, the vision that they lay out is one that we seem to be moving inexorably towards, barring the collapse of civilization as we know it. (Insert your disaster here.)
I'll go with "industrial collapse & civilization crash as triggered by the over-dependence on / rapid depletion of fossil fuels, especially oil and natural gas, overpopulation and radical climate change. ...generally speaking the mentality of a cancer cell ['growth for the sake of growth']" for $400, please.
