> How do we replace the work ethic that tells us we are our jobs and idleness is immoral?
For many people it has nothing to do with morality, it's hardwired into their instincts. They want to work, and they will work.
For a lot of us who are not excited about this future it's that no one is trying to answer all the questions you laid out. Instead we have the disgusting people at the helm purposefully spreading doomerism and saying, "We'll figure it out." I think it's pretty problematic (to say the least) to care more about technological advancement than how that advancement is actually shaping up to effect people in the short term. But I know many people don't care, especially those who believe they won't be among the affected.
