Polgar's central claim is that around age four, a child's brain behaves like a sponge and is maximally receptive to structured learning. Starting deep specialization after this window, in his view, leaves most of that neuroplasticity on the table. It reframes early childhood not as a time for casual exploration, but as the single highest-ROI period for skill installation.
