an AI does 95% of a job but a human is still required for the last 5%

This is the kind of scenario I was talking about in my initial comment. The naive assumption about this scenario is that it would result in 95% of jobs disappearing, but based on history it's more likely that we just do 2000% more stuff with the same amount of human effort.

And if AI really replaces 100% of human labor, are we really going to retain an economic system that only works when humans are doing labor?
