I particularly miss the feeling of being in control: with text I can skip scan, reread and so on with just an eye motion.

The first time I encountered the concept of a 3xer was in the context of political radicalization, people infusing their mind with YouTube self-radicalization content on 3x (or higher) every day. My mind conjured up images of Malcolm McDowell in that A Clockwork Orange scene, only that it's self-inflicted and with content aiming at the exact opposite.
