I'll try to be nice here, but the author is a fucking idiot.
To posit that the Bay Area can handle the population growth of sprawling and ill-planned Atlanta, Phoenix and Las Vegas is patently ridiculous. The Bay Area is already one of the most dense metro regions in the US and to think that the area could see growth like that without a MAJOR disruption in quality of life is absurd.
I also think many engineers, who can usually pick where they want to live, already find the Bay Area to crowded and have decided upon less lucrative opportunities elsewhere.
