Modularization, to put it simply, the biggest change for end users might just be two words: waiting. Previously, a single chain handled everything, and you just waited for it to get congested or become expensive; now, it's split up, which theoretically is smoother, but you start waiting for confirmations, cross-chain transactions, wallet pop-ups with a bunch of prompts you can't understand—"proofs"—and in the end, you still have to think carefully about which layer's security you're relying on. Recently, AI agents/auto-trading have taken the "waiting" out of the equation, outsourcing it to robots. It looks convenient, but in fact, the risks are also outsourced: I don't care much about who is promoting the narrative, I care more about how much you authorize it to do, and whether you can revoke it if something goes wrong. Anyway, I now prefer to be a bit slower, wait a few more minutes, rather than sign once and send myself into a chain of liquidations. Survive first, then talk about ideals.
