That will probably happen eventually but at that point, with UBI in place, we could increase the level to something people can live on. If, say, we get to a point where 90% of people can't find jobs, we really won't have a choice. Essentially we'll need to give the general population a share in the productivity of the robots.

In the meantime, with most people having at least low-paying jobs, we can start with something more modest.
