What is your snark free plan for dealing with the people displaced from the farms? Remember, the overwhelming majority of the labor force used to work on farms.
Speaking from the perspective of someone that descended from a farming/mining/manufacturing/computing family tree:
A bit of historical perspective would help.
The transitions from agriculture and (early) mining to manufacturing left a wide margin of time to retrain. International threats largely DNE while plenty of work existed to receive and integrate such individuals over time.
The transition from manufacturing to early computing represented a narrower escape. Early computing was an escape hatch that provided relative stability in a much shorter timespan. This point marks the beginning of the effort to reduce overall stability.
Today, the emphasis is in removing any remaining stability as it also represents a higher cost. The Aspen Institute's invention of the "sharing economy" buzzword exists only to sugarcoat the effort to remove any large-scale stability in work arrangements.
Want to know what works? Stop trying to remove stability from work arrangements.
