Maybe one can read about whatever interests you while also knowing a bit about everything so you can talk about popular topics with other people who may not have similar interests.
And you’re right, this isn’t optimal for all contexts. Very context-specific!
Hi! This is rhetorical. Books do not mean like you actually buying books, PDFs, or EPUBs. But more like don’t be afraid to spend money to learn, for instance, spending money on tokens so you can do more things with AI, for instance. Or spending money to travel to a specific place. Both are types of learning that do not have chapters. And we also live in a different world, like you pointed out. Many products have zero marginal cost like ebooks, etc.
