Read books, because the data rate of reading is much greater than when somebody is speaking. — Elon Musk

Read books, because the data rate of reading is much greater than when somebody is speaking.

Author: Elon Musk

Insight: There's something quietly radical about this observation. We live in an age of podcasts, TED talks, and influencers, yet Musk is pointing out something almost mechanical: reading simply moves faster. When someone speaks, you're locked into their pace. Even a fast talker tops out around 150 words per minute. Your eyes, though, can absorb information far more quickly when you're in control of the speed. You can skip ahead, reread a complex sentence, pause to think. It's why struggling students sometimes do better with textbooks than lectures—not because books are flashier, but because they respect your own rhythm. The deeper insight is that reading demands something speaking doesn't: your active participation. You have to decode words, build mental images, follow arguments on your own. This friction isn't a bug—it's the feature. It creates deeper processing and retention. In a world optimized for passive consumption and entertainment, choosing to read is choosing a slower, more deliberate kind of learning. That doesn't mean books are always better. But if you want to genuinely understand something complex, the math usually favors staying quiet and reading.
