Whether you are working or wasting time is decided by the pre frontal cortex, which is responsible for the decision making process in the brain. However the creativity is a whole-brain process, it takes many brain regions to come up with insights and inspirations. So it makes sense not to depend on your pre-frontal cortex to decide activities of the whole brain. It almost like uninformed non-technical manager deciding the technology stack for the programmers.
