Do you think that same result would have happened if horses had other skills outside of the specific skill set that was automated?

If horses happened to be really good at pulling carts AND really good at driving, for instance, might we not instead have even more horses than we did at the turn of the 19th century, just having shifted from pulling carts to driving them?

I’m not sure the inability of horses to adapt to changing industrialization is the best proxy for what’s going to happen to humans.
