Ya, my Grandpa didn't put his horses out to pasture when he first saw a model T, but he did end up driving a Plymouth.
Same questions Where is the gas going to come from, the tires wear out, there aren't gas stations everywhere, it will wear out, can't go in the mud, over rough ground, bla bla bla bla.
Same types of reasoning, there will always be lots of grass, a mare has a foal, I can buy plenty of good horses for that kind of money. My horse will never catch on fire.
