Starting over: Rebuilding civilisation from scratch - science-in-society - 28 March 201... - 0 views

  •  
    IN JUST a few thousand years, we humans have created a remarkable civilisation: cities, transport networks, governments, vast economies full of specialised labour and a host of cultural trappings. It all just about works, but it's hardly a model of rational design - instead, people in each generation have done the best they could with what they inherited from their predecessors. As a result, we've ended up trapped in what, in retrospect, look like mistakes. What sensible engineer, for example, would build a sprawling, low-density megalopolis like Los Angeles on purpose? Suppose we could try again. Imagine that Civilisation 1.0 evaporated tomorrow, leaving us with unlimited manpower, a willing populace and - most important - all the knowledge we've accumulated about what works, what doesn't, and how we might avoid the errors we got locked into last time. If you had the chance to build Civilisation 2.0 from scratch, what would you do differently?
