Instead of having smart workers that need to know about the full logic of how they operate and what they will do which makes it hard to reuse parts of those workers switch the model so that workers are dumb and they just run tasks which themselves can request additional tasks to run when succesful. This makes it more consistent when tasks are to be retried and also makes it easier to know which task is running and when. Less specialized workers == good.
