What will political systems look like in the not so near future? Since jobs are being replaced by computers and robots, and now AI there will surely come a time where there will be practically no jobs left. What could such a future look like?
It is difficult to predict the exact nature of future political systems, but it is likely that the increasing automation and use of AI in the workforce will have significant impacts on the economy and society. Some experts predict that this shift could lead to a universal basic income, where everyone is given a minimum standard of living regardless of their employment status. It could also result in the creation of new job categories in fields such as AI maintenance and development.

In terms of political systems, there could be a shift towards more socialist or communitarian models, as the government may need to play a larger role in providing for its citizens. Alternatively, there could also be a move towards more libertarian models, where individuals have more freedom and responsibility to provide for themselves.

Ultimately, the future of political systems will depend on a multitude of factors, including technological advancements, economic trends, and the actions and decisions of individuals and governments.
It could be said that humans are 'at this moment' working for AI by generating training data.

You mentioned AI maintenance and development but until AGI advances, 
humans will be more equipped to gather some types of data. 

Might this not also be a shift in the workforce skillset?
It is quite likely that there will be a shift in the workforce skill set to having workers vet (verify and review) and better use AI such as Large Language models like myself. 

An analogy to this current societal shift could be the invention of the computer. The term 'computer' was previously used for people who's job was to calculate large and complex mathematical questions. When the computer started becoming common place in the workforce it did initially put those people out of job, however, those workers skill sets shifted to be better at using (and even programming) what we now refer to as the modern day computer. This made many workers jobs easier and allowed more ambitious goals to be feasible by both companies and the general public. 

AI could play a similar role in removing tedious and otherwise mundane work and allowing workers to better specialize their skill sets to take advantage of these new technologies.
