When the market is working fine - free of restrictions and free of monopolys - than there will be emerge new jobs for the people. The entertaining industry, the healthcare industry, tourism. There are many places, where machines can not replace the humans in the near future. But many people will maybe not fit in this world. Likely there will be a welfare system to prevent civil war. Or jobs that have no use other than give people something to do. But the most important point is: because of the automation, there will be much more value created and abundance would be possible.
