Alexandra Pelosi’s documentary short “San Francisco 2.0” premiered last night on HBO and it’s a must-watch for anyone living in San Francisco or curious about all the housing/cultural/economic crises I keep droning on about.

The film starts cheekily enough with scenes from old horror movies warning of zombie invasions and showing San Francisco torn apart by monsters and earthquakes. Ms. Pelosi then cuts straight to her interviews with tech entrepreneurs and visits their converted shiny, playful lofts.

At first, their enthusiasm is actually uplifting and exciting. They are indeed creating new and useful tools, tools that we all use and have made our lives easier. Skateboards and coffee bars for everyone!

In one interview, she wonders how someone could be a billionaire if she’s never even heard of the company he sold. He says it’s pretty common; he also meets a lot of billionaires whose companies he’s never heard of.

And that’s the first sobering touch to the rest of the (very short) film. Ms. Pelosi interviews past mayors of San Francisco, residents who are being pushed out, and even small business owners who struggle to stay afloat due to tech’s expansion in the city. Ms. Pelosi discusses the massive increase in evictions, and tech’s skirting of regulatory laws. It’s a short film, so none of these topics gets the long rundown you’d expect in a longer documentary. (I was surprised at the tone of most of the city’s past mayors; I thought all of them would have seen this as a net positive for SF, echoing Mayor Ed Lee’s stance. They did not.)

After a real estate broker reminds us that San Francisco has always been a boom and bust town, what is most noticeable is how precarious everyone’s situation is. San Francisco comes across as a city waiting in the balance to see what happens next; where techies and non-techies alike aren’t exactly sure where they’ll be in five or ten years.  San Francisco is an extremely prosperous city, but it doesn’t seem like a healthy city.

A bright spot is when Robert Reich appears to give a wise economic and political analysis of San Francisco, using it as an example of a transformation that is happening world-wide. When he steps back and calls our current sociopolitical climate a form of social darwinism, you finally realize the term’s harsh reality. Everyone can’t win.
