We had computers since the 30's (before even), and software since the 60's. We also had factory automation since at least the middle of the last century, since you don't need computers automate factory assembly lines. Just needs some extra gears and switches. So this whole automation thing has been going on for most of the last 100 years. You are basically claiming that a tractor or a machine replacing 25 farmers or factory workers with 1 is not a problem, but a computer replacing 25 tractor drivers with 1 computer operator is. I don't buy it.
