> A 35 stories building with 1 bed-room condos can host up to 700-1000 persons. I'd bet lots of SF tech developers will opt for a very small high tech condo with amenities (pool, gym, library...) than the crap that is right now.
Sure, but you'll induce demand. As SF prices drop, think of all the people who will move in from (mostly) the East Bay. Prices will drop, but not nearly as much as you think without 100,000 units.
