Agree we will see more AI and improvements in productivity are welcome. It's how we advance. It's hard to imagine what the outcome for society will be as AI grows. It's something we will learn to live with. If it's an extreme shift we're facing then I think we'll see something similar as we saw when people were farmers. We got improvements in productivity and society changed and people started working in factories. 80% farmers became 3% farmers in relatively short time. This time we may go down to 3% of the people working in factories, but I believe people will find new sectors to work in. That's how I hope and think people will be able to get an income. We can all try and guess which sectors that will be, but we will probably be more wrong than right.
What new sectors? AI is largely self-developing. Indeed, the code generated by machine-learning systems is impenetrable. It cannot be debugged. It is expected, feared, or certainly anticipated that AI systems will reach so-called singularity, where they truly develop themselves, at ever accelerating rates, and it will be impossible for humans to track and understand it. There are people here who will be better able to explain it than me.
But the point is, there is little room for humans to oversee AI; nor manage automation (which instead will be managed by AI). Even now, AI is involved in such things as the automated creation of contracts. In what new fields do you foresee people working in such a society?
Now, maybe there are unforeseen things which will come into play to slow or halt this development. But right now, this seems to be where we are heading. I would think the two great limiting factors upon such developments and increased recreation time will be climate change and scarcity of raw materials. Though, climate change might reduce (read,
cull) the population, reducing some pressure there.
