You can not reach that post scarcity world without automation.

Human civilization is a process, a long term project. We cannot leapfrog stages. Ultimately suffocating or restricting technological advancement with the intention of preserving people’s jobs, while somewhat nobles, is a myopic approach to the issue. Don’t preserve any jobs, automate it all. Everything that can be automated should be automated. At some point redistribution of wealth won’t be a choice, it will be fundamentally necessary.
