Robots destroy far more jobs than they create. They don't require health insurance or healthcare. They don't pay taxes. They have no rights or freedoms. They form no unions. Stage no strikes. Protest nothing. They're the ideal worker. Their main competition comes from nations with low cost of living expense / low wages driving low cost of labor. Between outsourcing/offshoring of jobs and robots many established nations will lose millions of jobs which were once done by humans.
Some estimates claim 50% of all jobs are in danger of being automated someday:
Half of American jobs are at risk from automation, new study suggestsThe American workforce is under tremendous pressure, with change coming on multiple fronts. That uncertainty is leading to political and social turbulence, a new research paper suggests.
One in four American jobs are at risk of being shipped overseas in the coming years and about half could be replaced by automation, according to Ball State University's Center for Business and Economic Research. A new paper titled, "How Vulnerable are American Communities to Automation, Trade, and Urbanization?" combines several recent studies on employment trends to present a stark view of the future job situation for certain parts of the country.
"Some places and people observe robust benefits while others observe primarily costs" from the changes underway, the researchers wrote. "This has important economic, social, and political implications."

Permaculture, living off grid and similar topics also tend to come up in discussions on job automation.
