Human nature, with very few exceptions, wants more. Give a worker a partial free salary, and he won't need to produce as much. So, he will cut his days or hours back, and do more fishing.

His boss will have to get someone in to replace the hours or days he cut back. Then that guy will be given a partial free salary, and the cycle will continue.

This could be the way to gradually replace jobs with robots, until the robots did everything for us, and we had freedom to do anything that we wanted, and collected a free salary a hundred times greater than anything we earn now.

The problem with the robot idea is, robots haven't been developed that are expertise enough to handle much of anything. It will take time, especially to make robots that can repair themselves, and do the whole process of mining the raw materials, to making the finished product.

Odds are WW3 will destroy most of us before anything like the robot idea or free money idea can be pushed all the way through society.
