This does an excellent job connecting the dots with the needed historical perspective. Not a surprise. Unlike earlier use of technology to replace labor this does not create a new, reachable labor demand. The gap between salable skills and what the majority of displaced workers can achieve with available education, particularly in the US, is too big and growing. This is a direct goal of UBI as it would reduce the labor supply without undo suffering or civic collapse. The pressure to replace low wage workers would increase driving investment while purchasing powe also increases. The only other option is perhaps free education, that should be provided anyway in an automating economy, but that does not address the gap between mass capability and a narrower demand for highly trained design and maintenance engineers. Although with both incentives in place a new balance may be achievable in a generation or so.
