The ability to work less historically has always came as a byproduct of individuals earning more per hour through productivity increases.
The end goal of AI isn't to make your labour more productive, but to not need your labour at all.
As your labour becomes less useful if anything you'll find you need to work more. At some point you may be as useful to the labour market as someone with 60 IQ today. At this point most of the world will become entirely financially dependent on the wealth redistribution of the few who own the AI companies producing all the wealth – assuming they take pity on you or there's something governments can actually do to force them to pay 90%+ tax rates, of course.
