Recently, there's been more talk about sharding and parallel processing, and it feels like the same old debate from back then—"whose L2 TPS is higher, costs are lower, and subsidies are more generous"… While it's lively and noisy, I tend to focus on: who controls the keys when assets are deposited? What if there's a problem with the bridge? When it’s time to run away, can you withdraw smoothly, and not get stuck in a contract staring at each other?

My mom asked me a couple of days ago, "You guys said it's decentralized, so why do you still need to bridge?" I could only reply: Basically, bridges are the most likely to have issues, so think carefully about how to come back before you go. Anyway, I prefer to be cautious and slow rather than gambling with luck.
