It could take all dev jobs and all knowledge jobs, but leave most of the rest of the economy untouched. You know - the people in shops, fixing your car, patching up your house, etc. Robotics I think may be actually difficult (Moravec's Paradox) and take a lot more time and change a lot more slowly. There are physical constraints even if we know how to do it which means it will take significant time to roll out (expertise, resource for build, energy, etc).

i.e. all the fun creative jobs are taken but the menial labor jobs remain. It may take your job, but you will still need to pay for most things you need.
