I suspect that building more will not make a dent because everyone (at least everyone here in HN comments) assumes that more construction is the solution with _everything else_ staying the same. But it won't.
More housing will bring more people. SF is one of the most desirable places in the world to live, with striving economy, great climate, liberal culture and breathtaking scenery. Half of Americans want to live in SF, and probably billions world wide.
Building insane amount of additional housing units in SF, say 4,000,000, will result in Bay Area economy expanding even further, more companies will be created and the existing ones will probably grow faster. SF will completely eclipse NYC as the economic powerhouse and we'll have 5MM people living in skyscrapers with 1br apartments going for the same $4K/mo as they are now: see Hong Kong.
