This is definitely true. "Open-world" jobs are par for the course in the Western world, where deciding what you have to do is part of the job, along with predicting, strategizing, and reflecting. It is a lot more cognitively engaging and also heavy. Farming and mining certainly have aspects of this, but a majority of the work was drone work -- exactly the type of work to go first in automatization. What's left is necessarily cognitively difficult work.
