I got a giggle out of this. I grew up this way. True that was a while back for me but plenty of people around the world still live this way and it's not all in third world countries. The "long vanished past" starts when you were born for you but that's only where you are. Some people may still be living it.
Lots of homesteaders, maybe.
But very few, if any, commercial farms expecting to make a profit. Given that making a profit in farming is hard enough with every possible advantage that modern Ag science can provide.
