UBI now, would be essentially communism, eventually globally, and ever more invasive. Ford (and perhaps Edison) essentially defined money as based upon energy and one's time. So presently UBI would just be providing promises for the time of others to those whose time is unwanted.  The idea that machines will do everything is being used to sell the UBI-communism.  AI is presently very dumb; and as there's no guarantee it will become smart (strong ai). It also allows a leftist government to centralize control and decide who has what value. (There would be grievance payments.) Think of leftist abuses of liberties now, versus if they controlled all income. One's time will always be a scarce and source of wealth to those who make something of themselves.
