The sky did fall. The protestors of the 1800's were correct. The people displaced by technology in the 1800s fell into poverty and early death, and England, for instance, was home to immense poverty and despair. We don't want to remember, which is not the same thing as not-happened. We choose to remember the happy industrialist and middle-class lifestyles which came from impoverishing the workers, not the majority of miserable people they created by re-distributing the wealth from the majority of the working people to their own class.
thing to remember is that the people who were protesting their replacement by machines weren't really asking for history to be rolled back - they wanted to be *cut in on the profits* created by removing them from the books. They wanted some income redistribution. They lost. Since they didn't run university history courses, as industrialists did, they have been expunged from our collective memory and rendered into silly people who didn't want to stop making horse collars by hand.
The price of all this will be misery, violence, hunger and early death for hundreds of millions of people, eventually, if history repeats. Looks like "yes". And no one will want to take notice, other than intense coverage of the violence in the "bad" neighborhoods.
