You can edit a cell perfectly, and it still turns out useless. The gene is fixed exactly as planned, yet the cell behaves unpredictably: it drifts, changes fate, loses safety. It's like fixing one gear in a watch, but the watch still runs wrong because the whole mechanism is out of sync. Previously, a cell was viewed as a list of independent parts.

An orchestra without a conductor. Each musician plays their own part, and the overall volume builds, but the melody falls apart — violins rush ahead, brass lags behind. Cells behave much the same way when their DNA is modified: they may shift, but some move far, while others stay put.

A person hunting for keys mentally runs through places where they might be. A bird that tucked hundreds of seeds into crevices in autumn retrieves them flawlessly in winter. How can a brain hold so many addresses when all birds have roughly the same number of neurons? The answer lies in geometry.
