> You're thinking in short, next twenty years or so I suspect the drawdown of easily-accessible, dense, cheap fossil fuels will spell the end of global integration; consider a very low-energy future where most communication takes place via radio and travel for 99% takes place at a fraction of today's rate. We would expect regional differences to increase as groups adapt to local areas, ideally while carrying out extensive sharing of e.g. practices and techniques.
