Do you really think the proportions of that are going to work out? That laying off a thousand farm workers will somehow generate a thousand replacement engineering jobs (and that these farm workers will somehow get trained to fill them)?
They will not be laid off in such numbers because there is little economic incentive to do so. Machines cost a lot of money. And they require maintenance over time. You have to realize how little these workers make. Paying US rent full time a person could barely afford to feed and shelter themselves on the money these workers make.
We are talking 50 cents a bucket. Pennies per item. There is not a lot of room for automation to undercut.
Workers in decision making and diagnosis type roles cost significantly more and mostly only require software(not hardware) to replace. Think about how much a doctor gets paid per cancer diagnosis? Or per cancer treatment prescribed?
