Homo sapience had a long period of its history when it was crucial to have a well developed body. Today we need to perform useless exercises just to maintain our bodies in somewhat acceptable shape. This might be applied to intellect as well.
In the coming era of unnecessary intellectual power we might need to do thinking exercises as something that helps maintaining a healthful (and beautiful) mind though our core values would shift towards something else, something that is regarded as good but not mandatory for personal success today.
