The word "modularization" sounds very mysterious, but basically for ordinary people, there are only two direct changes: one is that the blockchain might become cheaper and smoother (no more frequent slowdowns and exorbitant fees), and the second is that "which chain to use" may increasingly resemble choosing a network entry point, and you may not perceive how the backend is split. The cost is also increasing: more bridges, more layers, more points of failure. You need to be clearer about which layer or chain your assets are on, or you might not even know where you lost them.

These days, I see everyone guessing whether the ecosystem will migrate before and after a major public chain upgrade... I actually think migration doesn't matter much; what's important is whether your positions are built on the illusion that "it will never go offline / never have issues." Modularization is not a get-out-of-jail-free card; at best, it allows you to swap modules or fallback points faster when problems occur, but the risks you bear won't automatically disappear. Anyway, for me now, I try to cross chains as little as possible. If I do cross, I treat it as one more step that adds a little more uncertainty. That's all for now.
