I've also been thinking about modular blockchains lately, and what exactly has changed for us end-users. To put it simply, you still click buttons and make transfers as usual, but the real change might be that behind the same operation, you can choose a cheaper/faster "route," and different applications can select their suitable execution layer and data layer, instead of all sharing a single main chain. The benefit is a more stable experience and more controllable costs, but there are downsides too: more chains, more bridges, more confusing prompts, and when something goes wrong, you won't even know who to blame... Anyway, my current approach is still the old routine—test small transactions first, then scale up, rather than going all-in with full positions to "experience the future" right away. Also, recently, the on-chain data tools and tagging systems have been criticized for being laggy or misleading, and I can relate: the more fragmented the modular system, the more the information feels like fog, and the more you need to keep some skepticism.
