What this video covers
Both are about "how many", but they measure different things. Hick's law is about choosing - decision time grows with the number of options. Miller's law is about holding - working memory keeps only about seven chunks at once. One is speed of choice; the other is capacity of memory.
Drag the count up and watch them part ways: Hick's time climbs in a gentle curve (deciding gets slower, but never impossible), while Miller's memory hits a wall around seven and tips into overload. Same number feeding two quite different limits - which is exactly why people muddle them.
