It is a good thing that we have an economy where there are jobs for people to do things that 'don't need to be done'. This is the only way that a highly specialized capitalist society can provide income and purpose for everyone, and drive further innovation. People need income and jobs, even as we add more automation. As long as our society produces enough basic needs to actually support people, it is better that people are doing 'unnecessary' jobs rather than being unemployed as the result of automation.
Everyone is worried that automation is going to steal people's jobs, and jobs won't exist anymore, but that has already been happening in full swing for 100+ years. 'Useless' jobs are and will continue to be the solution to that problem.
(And I am using 'useless' rather tongue-in-cheek. The jobs do have real functional value, even if they're in higher parts of Maslow's hierarchy)
