Regarding the the OPs question "If AI eliminates all of the jobs what will everyone do?"
In my country, fifty years ago, the unemployment rate was 5.22%
It peaked in 2020 at 6.44%
Currently it is at 4.2%

Over the last fifty years many job types have been lost due to technological advancements in areas like automation, robotics, etc.
Many new job types are being created as a result of emerging technologies.
Even with all the changes going on unemployment is constant within a couple of percentage points.  People are still in work, what changes is what that work is.
