Technology and artificial intelligence have advanced so much that many traditionally human-held jobs are now performed by robots and this trend toward automation is only gaining strength. Thus, human workers are gradually becoming obsolete, including those with roles like restaurant workers and truck drivers. Automation has already caused an increase in unemployment, as the number of jobs available to humans simply diminishes. According to Elon Musk, founder and CEO of Tesla and SpaceX, eventually the only option will be a universal basic income (or UBI) for the whole country. With UBI, each person receives a regular check from the government.
