Modularization, to put it simply, gives ordinary users two main feelings: cheaper and less hassle (in theory). After separating the execution layer and data layer, L2 can choose a more suitable "warehouse" to store data, and during congestion, it won't be a mess, so after running across several L2s recently, transaction fees and lagging are indeed not as mysterious as before.

But I have to complain too: do you think modularization makes things more fair? If the ordering layer hasn't changed, MEV will still squeeze you in the middle, and it's not wrong for retail investors to complain, "I click a transaction and still have to rely on luck." When miners/validators see their income drop, they want to make up for it through ordering/packaging, which results in a feeling of "who gets taken care of first." I'm now trying to use protected routing as much as possible, splitting orders when possible, and not squeezing into the same block as large orders... for now, that's it.
