Is the Future Amish?

In this commentary from Salon (excerpted below) Garrison Keillor muses how climate change might lead our grandchildren to live more like the Amish:

You look at the Amish and you see the past but you might also be looking at the future. Our great-grandchildren, faced with facts their ancestors were able to ignore, might have to do without the internal-combustion engine and figure out how to live the subsistence life. Maybe someone will invent a car that runs on hydrogen, or horse manure, or maybe people will travel on beams of light like in old radio serials, but the realist in you thinks otherwise.
