I reject the premise that San Francisco should be planning for an ever-increasing population.<p>At some point I think that San Francisco should look at itself and say &quot;Hey, we&#x27;re a small, earthquake-prone hilly penninsula, we can&#x27;t expand outwards. Traffic flow is constrained by planning decisions made a long time ago. We&#x27;ve got a pretty good quality of life as it is, and lots of nice historic buildings. Let&#x27;s just put a lid on it and declare we&#x27;re basically full&quot;.<p>Many of the nicest cities in Europe are ones where at some point in the past they&#x27;ve decided to stop building in the historic city centre and just leave things as they were at some particular point in time.<p>If anything I think San Francisco needs <i>fewer</i> people. San Francisco should focus on quality of residents, not quantity.
