As a failure mode, “vague, useless, or trivially-obvious suggestions” is less of a problem than “rapidly eradicates all life.” Historically, projects that were explicitly designed to be safe even when they inevitably failed have been more successful and less deadly than projects which were obsessively designed never to fail at all.
