To me THIS is the crux of the problem. Basic Income is only needed IF there won't be enough jobs left. Which is an actual possibility. BUT history predicts otherwise. So the question is: Is this time different enough? Is this the moment that automation gets so good, people aren't needed anymore? ... I don't know.
True, but I doubt new jobs will be invented in the same number. Also those new jobs will demand a much higher education/qualification which is fine but then we have to make sure the poor will have access to higher education which they currently do not have for several reasons.
That's right, at least as far as technology goes; by design, all tech that increases productivity will produce fewer new jobs than the ones it displaces. They will be better/more desirable jobs, but fewer. The previous workers aren't always well-suited to be retrained from box-packer to SCADA programmer, their kids, maybe so, but you've still got the ones who were originally displaced left to euthanize.
First, the poor don't need access to higher education, they need access to better primary education. The technology training in most public schools is pathetic to non-existent.
Second, why would you doubt for a second that new jobs will be invented? Until AI improves there will always be a plethora of menial information technology jobs that would be the 21st century equivalent of assembling widgets.
