Point of how the current world needs more generalists. How the notions of head start and hyper specializations are irrelevant in current context. What can we do to expand our range.
Author discusses two models of learning/training. One is specialized, block learning which produces immediate visible progress but harms long term ability. Blocked learning makes it difficult for learners to identify abstract patterns and apply them in test environments that mimic reality. Other model is mixed-up learning where learners are instead forced to identify patterns and not restricted to the correct approach at first instance.
In conclusion, slow learning with interleaving, desirable difficulties and spacing is tough, can be frustrating and may not produce immediate, localized results. But it will produce enduring knowledge and more able general problem-solvers.
Author explains how knowledge outside your own domain helps solve problems. Examples of analogies with abstract ideas enable outside view to inside problems.
