Not a worry. No more than a small percentage will ever try paleo eating.

A more likely scenario is for highly intensified agriculture, high
input on small acreage, to gradually replace our current extensive
style. I doubt this will occur either though, as there is no current
rationale for it other than the ideology of a small number of people.

I live in flyover country. I find that urban people
romanticize/fantasize about rural life and agriculture. In fact, we do
it the way we do it now for some solid reasons. If we have to change
in the future we will, but not until the economy changes to allow it.

A lot of the less desirable aspects of modern farming came about
because of government mandates and other meddling. Farmers have always
used small amounts of grain to finish cattle, but it wasn't until the
government got into subsidizing grain farmers to overproduce that
there was such a reliable surplus that it became the norm to
grain-feed cattle.

I don't see us changing our governing structure any time soon.
