And there is a philosophical tradition going back hundreds of years concerning efforts to bring about such a world. That tradition is leftism, and while some interpretations have led to calamity, analysis of those outcomes shows that the problem was concentration of power. If we can have decentralized leftism, which generally falls under the label of anarchism or anarchist communism, then we can according to theory build the world I describe.

I tend to avoid these terms because they start flamewars, but since you suggested only you and I think this way I wanted to draw your attention to these traditions.

I boil all that down to less charged phrases like "community ownership of the means of production". It is through an economy described in that way which I believe we can achieve the world we desire. As long as there is an ownership class and a worker class, even with UBI or other schemes, there will be those that hold all the cards and those masses fighting for scraps. But if we can find collective ways to distribute ownership rights over the core systems in the economy, then we can all enjoy the dividends of factory ownership and see the gains that come from growth in technology and automation. I think this is more eminently achievable and sustainable than some hand-wringing capitalists would have us believe.
