When the question of “automation caused job losses” comes up, most people think of industry jobs where production-line or humanoid robots take over jobs whole or at most talk about virtual assistants or other entry level knowledge-worker positions getting replaced by Artificial Intelligence or how Neural Networks can compose news articles from a set of facts; the common theme here is bots taking over jobs whole; while ‘bots taking over jobs at the production-line is old news and vending machines that replace pizza restaurants from the cashier to chef is no longer something to speculate, I think a much more deadly and silent job killer is often overlooked: tools that makes workers more efficient.
As a general rule, efficiencies that reduces work-hours by any given percentage, it also reduces the overall number of position by the same percentage.
