It's impossible that a 100K techies descending into SF after 2010 could have any impact on anything like the 18000 SRO units that used to house all those folks in the Tenderloin. All that wealth sloshing into a city - gentrification is a liberal fantasy.

Of course, when you bring up Manhattanizing Mission, most of these "YIMBY" astro-turf types start screeching. They want theirs, and as soon as they get it they'll be pulling up the ladder behind them. But keep your filthy mittens off the Mission.
