I'd argue that we'd probably need a lot more. Diagnoses would be more accurate so people would be inclined to use the health system more. Health work would be cheaper because the expensive doctor component would be used less. Time to go to the doctor could be more efficient (still working through the car ride) so people are even more likely to go. Overall that could likely mean higher demand for healthcare, including the human component.

Your food shopping point still needs middlemen. You have "chain of trust" issues with the producers. How do you know that you'll get good oranges from the orange grove. Who capitalizes the distribution system and designs the business model.

Considering historical examples, we'll see more use for people in the economic problems that are still machine hard. Machine easy economic problems will converge to resource costs + any premium for monopoly. This will free up more demand for other products. People still want to buy an easier, better life.
