We all buy stuff, washing machines, cars, TVs. and we all look round for the best price. Basically we, as buyers, are forcing prices down. It stands to reason that the suppliers will try to cut their costs so they can earn a profit and, in turn, lower their prices to compete with competitors who also want us to buy their stuff.
Robots are already replacing manual assembly lines. Robots run 24 hours a day 7 days a week and don't take a holiday or a sick day or go on strike for better pay.
AI will take your job one day and it's all because we keep demanding higher wages and, as buyers, drive prices down forcing suppliers to use robots, AI or cheap labour to supply at a price we're will to pay.
