Blue LEDs are the absolute worst.

Seriously though: I've been in the position of worrying if my lack of a cell phone will mean I can't enter buildings anymore. I've got friends who worry about embedded computers that are keeping their hearts running, that use software that is impossible to audit or improve. I've purposefully hacked my focus (in the opposite direction as seen in this book, and without using tech or meds). So there's a lot of stuff in this book that I'm very happy to see engaged with in the way it is here. This was mostly a 5 star read for me, dinged a bit for being a bit too simplistic at the end maybe.
