Rubin's forced reduction (100→40→70) and Musk's deletion algorithm arrive at roughly the same place but teach different things along the way. Rubin's frame works from the rebuild side: overshoot the cut, then re-introduce what earns its place—you discover what's true by killing it. Musk's frame works from the cull side: assume everything is non-essential until it defends its retention—you discover what's necessary by forcing the defense. Both treat the 10–30% re-add as evidence you deleted the right things, not as failure.
