Inbetween the current world full of labor scarcity, and the philosophical dilemma "what do I even do" post-scarcity utopia, is a world similar to our current one with much less labor scarcity and much more quality of life. That's what we're aiming for right now. What comes afterwards we can worry about then.
Quality of life for who, though? That's kind of the point of all this back and forth isn't it? Because if prior examples are anything to go on the likeliest outcome is we're talking about further increasing QoL for a small minority of individuals who least need it at the expense of basically everyone else.
According to the Pew Trust (and my own personal observations) the middle class has been shrinking more or less steadily for the last 50 years. Through what mechanism is eliminating existing jobs expected to reverse this trend?
