Department of "Really???"

From The Oil Drum:

Over the very long term, it seems to me that businesses will be much smaller and more local and there will be a great deal more manual labor. There were be differences of opinion on what the world may look like, and what time frames will be. Possible outcomes:

--Electricity / no electricity
--Water / no running water
--Electric cars / solar cars / trains / walking
--Current countries / new country boundaries
--Tractors / Draft animals

Should we be preparing for this change now? What career choices do you see as reasonable ones? What educational choices should people be making now?

REALLY??? In our lifetimes??? Could you in good conscience tell a college freshman to "try to focus on careers that don't rely on electricity"???
