I recently realized that whenever I see words like "data availability / ordering / finality," I instinctively want to close the page. But then I thought, there's actually just one main thread: you think you're dealing with "reality," but you're actually just dealing with a version within a certain sequence. Whether data can be seen by everyone (otherwise you have no evidence even for review), who is in line (are you at the front or pushed to the back), and whether it finally counts (don't treat a momentary illusion as the conclusion)... Basically, you're trading "confirmation" feelings.

These days, cross-chain bridges have had issues again, which makes me even more sensitive: once assets leave, waiting for confirmation becomes collective self-comfort. And then there's the oracle suddenly reporting an outrageous price, with a bunch of people in the group saying "wait for a few confirmations," sounding very rational, but every time I wait until the price no longer waits for me... then I just sigh, slippage feels like fate, so I just put my hand back into my pocket.
