98% of US population used to be farmers for sustainability. Automation of farming freed up that workforce, today only 2% of the population directly farms. That (insanely high) percentage of displaced workforce is what allowed other other industries to spring up. Yes, jobs don't exist for those 9k workers - but the workforce being freed is exciting as it opens up entire potential markets that were simply impractical prior. There will always be growing pains - how do you retrain a cashier to be ~anything else? Same with Toll Booth workers on highways and the like, what else will those people do? But that's where the Govt should step in, ease the point edges of progress. Free market is great, but it does leave significant portions of individuals behind in the shortrun.
