The problem is that your roadmap requires things that don't exist yet or only exist at prohibitive prices, and it's not knowable how much time or money you will need to solve either one. So a concrete roadmap is impossible.
Advanced robotics would need to become quite cheap for them to become more affordable and convenient than a minimum-wage employee. And physical fields like materials engineering are known for moving quite slowly and at their own pace, so I'm not sure how much automation could help there.
That's the last barrier we have right now that prevents the total obsolescence (and therefore destruction) of the common worker.
