Back then, it would've been, like, the one guy at the factory who knows how to read, reading things to fellow workers, right? So reading theory would've been to a large degree a social activity back then, whereas now it's often a pretty lonely activity. Even if you aren't just reading alone, but are doing a book club or something... a book club isn't quite the same when it's 12 people from around the world on Discord, compared to when it's 12 people in the room with you. And even if you're going through the effort of making the information you learn more accessible to others, making an audiobook for the consumption of countless anonymous people online isn't quite the same as reading something to someone in person; nor is translating a work and publishing it online quite the same as actually going through the effort of making a translation in paper and giving it to someone.

Basically what I'm getting at is that "theory" can and should be praxis in itself, and this is achieved by changing the ways we interact with and think of "theory". That is, sharing information can itself be a productive, creative, and social activity grounded in our immediate surroundings, that builds the networks and skills to make us good revolutionaries, rather than just giving us explanations of why the world's kinda messed up so that we can debate with internet strangers to prove who's more well-read.
