You don't need jobs as long as you have land, renewable energy sources and robots (and 3d printers). You can live in a community that is self sufficient. You will be employed by your land, as it always was up until 100 years ago. We will also have robots, maybe not the latest generation, but we don't need to go back to the 19th century agriculture.
It is you who will benefit in the end, if you can use AI to improve your life. As long as AI doesn't remain locked in the hands of one entity and we all share into the benefits, it will work out ok. In the short run we need some sort of social welfare though, and to invest in renewables and self-sufficiency technologies.
How much self-sufficient a country, city, village or small farm could be? There is a lot of potential to migrate back to small community agrarian economy with robotics and 3d printing and solar panels.
<speculation>People could trade using a different currency than that used for robotic produced goods. This currency will have to enforce differentiation of economic agents (diversity) and integration (low barriers of entry). A currency that will automatically disable the accumulation of power in a few hands and work for humans. We have to build an economy that functions more like the brain. In the brain there is no master neuron. They all share in the activity. So should be an enlightened human society.</speculation>
maybe low and middle class will have to serve people from high class who will have robots.
The jobs can can be lost - those will be lost and should be lost. Prolonging the process doesn't help anyone as well. The transition can be hard and painful, though, so speeding it up is all the better.
if jobs should be lost, I suggest you to leave you current job. and I'll want to see where you're going to get money to buy food.
"I'll get fired, won't have money for living and AI will take my place, but the world will be better! Yes! Progress!"
Who will benefit from this? Surely not you. Why are you so ecstatic then?
