The implication from this litter of thinkpieces on HN is that proximity to a tech hub (SV/NY) is your only competitive advantage as a knowledge worker—your butt is close to their chair. This runs counter to the other prevailing wisdom about SV/NY, which is that those areas are hubs—and essential to the tech industry—because the world's top talent is drawn to it. So which is it?
At the same time, many people prefer to live near one of those hubs whether because they just like NYC, Boston, Austin, Bay Area, Seattle, etc. or because they believe it gives them more flexibility in changing employers. (And/or being in proximity to many like-minded individuals.)
