You know who isn't being replaced? Fast food and retail workers. Low skill and super-high skill jobs are fine, but the middle-skill jobs are being automated out of existence. Perhaps these IT tools we all develop will eventually open up new mid-skilled employment opportunities, but when I see the anger and populism fueling Trump and Sander's campaigns, I see people who are genuinely hurting because they are being left behind. We can't just shrug and tell ourselves, "Well, it's always gotten better in the past."
