Earlier quoted context omitted.
I'm guessing that manual labor will be a thing of the past, and I struggle to see how this is a bad thing overall. If the same work is being done without human intervention, why not just give people who're unemployed the products of that labour?
Because the entities that control the machines and give their products away will be outcompeted by entities that keep the products to fuel their own growth. Over time, the former kind of entities will die out. This is a general argument, the "entities" could be rich people, companies, governments, AIs, etc.
We're not fighting with rich men in possession of robots; we're facing the entire machinery of capitalism, and this is still probably only a mask of an underlying process that optimizes for growth and competition. So far our goals and the goals of this process are more-less correlated, but in the future those goals may diverge and the process will continue unhindered in a fully automated world while we die a slow, painful death.
I've been thinking about it for some time. I'm afraid that, of all the things we fear, we might end up getting fucked by game theory. Anyway, I recently found a nice writeup on the topic by someone much smarter than me, which elaborates on this problem [0]. (warning: it's long, but worth reading)
