Slog tipper David points out this very intelligent essay by Neal Stephenson about how we put a man on the moon and then immediately stopped dreaming big:

The Deepwater Horizon oil spill of 2010 crystallized my feeling that we have lost our ability to get important things done. The OPEC oil shock was in 1973—almost 40 years ago. It was obvious then that it was crazy for the United States to let itself be held economic hostage to the kinds of countries where oil was being produced. It led to Jimmy Carter’s proposal for the development of an enormous synthetic fuels industry on American soil. Whatever one might think of the merits of the Carter presidency or of this particular proposal, it was, at least, a serious effort to come to grips with the problem.

Little has been heard in that vein since. We’ve been talking about wind farms, tidal power, and solar power for decades. Some progress has been made in those areas, but energy is still all about oil. In my city, Seattle, a 35-year-old plan to run a light rail line across Lake Washington is now being blocked by a citizen initiative. Thwarted or endlessly delayed in its efforts to build things, the city plods ahead with a project to paint bicycle lanes on the pavement of thoroughfares.

Please go read the whole thing. And read Stephenson's new book, too.
