Humanity is having those discussions, heck you are in one RIGHT NOW not some Hollywood future.
What is coming of those discussions is the ownership class balks at the idea of raising their taxes (see recent interview with bezos), and therefore balks at the idea that you or I should have any value beyond what we produce... And if AI can replace you or I, well how do we survive if we can't produce in a technological society?
In the (probably unlikely) event that AI use results in a post-scarcity economy in which there's no need to work to survive, a lot of people wouldn't regret sentiments like the ones in question.
On the contrary, it would mean they could work on whatever they please, including potentially standing on the shoulders of giants - the AIs - and seeing even further.
If we actually worked to create a society that work for the benefit of all its members, there would be a lot less reason to worry about developments like these. Much of the worry arises because for various reasons - none of them really good ones - we've ceded control of these developments to the people least suited to manage it.
To a society that provides a livelihood to all humans, equally?
For, I would love to hear how we get from here to there during an era with the largest wealth disparity ever seen in human history. (Yes, it's worse than the robber Baron era of US history). For I have yet to see any signs that the capital/ownership class has any intentions other than vacuuming up even more wealth and power for themselves. And that anathema to your desired outcome.
i wonder if this is physically/mathematically impossible: the mere act of living involves processing energy, and therefore doing work :)
And there is a lot of energy to be processed in this Universe before the heat death...
Mind you, there are places in the universe that we have no way of knowing ever existed... The non-obserable universe if you will. For when physicists talk of the observable universe, it is only the fraction we have any chance of receiving data/light/radiation of/from
This "any" shines like a thermonuclear fireball.
