Once robots are able to do everything that humans currently do, thereby rendering humans redundant for work and earning an income, will everything become free, or will a few people make all the money in the world because they “own” the robots, and allow everyone else to starve to death?
You are assuming that the non-robot owners would just sit by passively and allow the robot owners to decide their collective fate. At a certain point, if the robot owners did not take steps to at least placate the non-owners, the non-owners would rise in rebellion. What form the rebellion might take is another question: Kill or enslave the owners? Take over the robots? Destroy the robots?
Or they could just move somewhere and start up a robotless society of their own.
Or perhaps the robot owners won’t want to have anything to do with the huddled masses and will take steps to isolate themselves from the non-owners, leaving the non-owners to work for themselves.
If the robot owners had all the money, they would also have all the security forces. Haven’t you seen any sci fi films?
Unless land became free, it would be difficult in our world to simply move and start a robotless society. All the land is “owned” by someone or the government.
Perhaps I erred in saying that they would allow everyone to die. More likely that they would allow people to eke out miserable lives much as people already do that don’t have money. Just be a lot more of them.
