People who work for wages buy things, theres hardly any dispute to that.Yes high paid technicians are needed to service the machines, but they are approaching self diagnosing programs that will even limit the technician to a parts changer.Bots will not go away we wouldn't want them to.I was awestruck by a floor cleaning machine that did its work, then put itself away.That gives the domestic engineer, time to shop in the comfort of a recliner, and wait for a drone to drop off the purchases.We are in a consumer driven economy, and with a shrinking middle class, the buying power also shrinks. I'm in no position to loose sleep over the problem, with age needs and wants go down.
