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?

It all seems to boil down to the mind, and where you stand on the mind-body (none?) issue. These days I'm tending to be far more accepting of the unified view that dispenses with the duality.
The un-settled mind is prone to distraction, naturally.
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).
Modern monks at least have almost no unstructured time, or freedom to select a new task merely because they're tired of the current one. I don't know if this is how medieval monks lived but I suspect it wasn't that different.
So I suspect boredom in its usual sense is not part of the experience, because "nothing at all" isn't an activity that they do. Almost their entire long day is specifically allocated to focused tasks. I'm sure their minds wander during prayer and attention flags during routine toil. But they have no freedom to choose something else, and so never get to do something like read a book "out of boredom."
Also, monks are praying the whole time. All the time. They are usually repeating a short prayer in their minds while they work, while they walk, while they eat. All the time. Of course, they get distracted and their minds wander (especially the newer monks), but the aspiration is to "pray continually". They aren't just letting their minds wander around and think about whatever they want. A lot of their effort and attention goes into constantly guarding their minds against distracting thoughts and re-focusing on prayer.
Monks (Orthodox Christian monks, anyway) do, indeed, have freedom to choose something else, but the whole point of their ascetic struggle is to ignore those impulses and to stay in prayer.
As it's been noticed here, surely monks were not distracted by the same technology and at the same scale we are distracted to in today's world. When I came back to the "real world" from this experience, I could realise how much one life's was just constantly distracted.
