The thing is, the idea of cars cars being a plus for humanity is still debatable to this day. We won a lot in some areas but lost an awful lot in others.

That's a ridiculously cynical claim. And even if it were true, it still misses the fact that horses and the entire economy built around them stood no chance in the end. Today we are again in the sitation where many people who are alive and working today will have to consider getting reeducated if they don't want to be left behind, whether they want it or not.
