Lately I've been looking into IBC / cross-chain messaging. To put it simply, "one-time cross-chain" isn't just about transferring assets; it's about transferring trust: whether you believe in the finality of the source chain, whether the light client/verification logic has vulnerabilities, whether relayers will play dead, how the other chain handles this message, and further down the line, the application layer's own permissions and replay protection. Bridges are even more straightforward—basically packing trust into multi-signatures / validators / oracles... I tend to see simplicity as a trap, and when I see "seamless one-click cross-chain," I get a little nervous.

By the way, during the recent extreme fee wave, the group was arguing whether to reverse the trend or keep squeezing the bubble. My feeling is: the more extreme, the more it resembles cross-chain—you're not really betting on the direction; you're betting on who collapses first or which part can't hold up. Let's leave it at that for now, and be less hopeful.
