Modular chains sound very tough, but for end users, it boils down to two things: first, the signing in your wallet remains basically unchanged, you still click "Confirm"; second, you're more likely to encounter "this chain is fast but the bridge is scary / that chain is cheap but occasionally stalls," and the experience shifts from "choosing coins" to "selecting a package deal." Engineering-wise, separating consensus, execution, and data feels great, but from the user's perspective, the experience is: more dynamic fee structures, more frequent cross-chain interactions, and when issues arise, it's easier to blame "whose fault is it." By the way, looking at the community debates about privacy coins / mixing compliance, I feel that modularization will cut the boundaries even further: it's not about whether you want privacy, but about which layer or service you use, and ultimately who is responsible... Anyway, I just want fewer paths now, avoiding cross-chain if possible.
