Lately I keep seeing people talk about "data availability/ordering/finality" as if it's some kind of mysticism. Actually, just follow one line: the interaction you see on the chain—can it be verified by everyone, can someone insert a delay or change the order, and will it ultimately be reversed? Basically, it's about "Did I see it?", "Who came first, who came later?", and "Can it go wrong?"

These days, AI agents and automated trading are also quite popular. Some people are wildly promoting "fully automated profit-making," but I care more about which RPC they use, how large the signing permissions are, and whether retries will cause chaotic transactions... No matter how grand the narrative, in the end, it all comes down to that one transaction in your wallet.
I personally trust data more than intuition because it's simple: intuition can distort during volatility, but data at least helps me keep a safe distance from liquidation points and feel more at ease.
