There is a good analogy to weight training here. A sports team doesn’t use bodybuilding (maximum hypertrophy) techniques, or powerlifting (max strength) they use functional power training like Olympic lifts or power cleans. If you only had powerlifting it would be better than nothing, but it’s not as good as the best. Similarly, perhaps it’s beneficial to view calculus as “brain training”, but that doesn’t mean it’s the best modality. For example I think Statistics could provide the same challenge, while also being more applicable to the real world.
