Because the battlelines are always shifting, you're going to want to take in information too. But you don't have time to do that in the sort of detail you'd need to make sure you're quoting things in context, let alone slow down enough to read an actual book. But it isn't gonna matter cos, again...

most of the people you'll be fighting with/collecting dopamine hits for "defeating" are going to be doing even less than that. Which puts you in a spot where you begin to feel like the smartest person in whatever thread you're in. Expecting all criticism to follow the same form.
