> Avicenna apparently had a very strict schedule of putting down the quill and enjoying the company of his women. So now, the fact of his genius notwithstanding, what does that do with the dopamine and distraction theorem given this man was unbelievably productive in his life?

Probably not much. I forget the exact term, but when people refer to "dopamine" in the contact of distraction, they're not really talking about dopamine in general, but rather things like slot-machine-like random enforcement engagement mechanisms (which can be explicitly designed, like in social media apps, or accidentally "fall out" of new tech-enabled activities).
