There is an article on CNN.com about these two billionaire investors and their thoughts on various oil price scenarios. After I read the article, it reminded me of a conversation that I had with my sister a week or so after hurricane Katrina. What would happen to society if oil suddenly became so scarce and expensive that it wasn't possible to continue its everyday use? Would suburbs continue to exist but turn into self sufficient villages around larger cities? Would there be a panic and mass exodus to the big cities? Would science be able to find a suitable replacement in time before society collapsed? Maybe society wouldn't collapse at all, but watching New Orleans deteriorate into a war zone in less than a week didn't give me much hope.
Of course all of this is completely uneducated speculation…and probably a little silly.
