The modular chain is hyped up a lot, but frankly, the most direct changes for end users are just two points: whether transactions can be cheaper and smoother, and whether the mental burden of the cross-chain/bridge stuff in their wallets will be reduced. Other "architecture upgrades" are hardly perceptible without looking at the data. Anyway, I’ll be watching: for the same work, is it ultimately being taken by a few schedulers/validators—recently, everyone’s been complaining about miner/validator income, MEV, and fairness in ordering, which is basically just a different shell for the same issue. The so-called "breaking it down" theoretically adds a layer of checks and balances, but don’t be too optimistic; in the end, it still depends on the concentration of power and rule enforcement.

My current mindset is a bit like making backups: don’t expect a narrative that never loses its file; the more paths you leave, the better. When something goes wrong, at least there’s a place to retreat to. Otherwise, "modularization" just means spreading the pitfalls across several components to step on together.
