It’s almost like a third mode for your brain to exist in has been created: reactive mode. In reactive mode you have the illusion of control, but your attention is more often than not under the control of an algorithm. It sort of looks like focus, but there’s no deep thinking. It sort of looks like mental relaxation, but your mind is not free to wander and proactively determine what it will think about. You are stuck reacting to someone else’s agenda.
