His argument about digital watches did not age well.
My kids have known how to understand a digital clock since they were toddlers, but even now, in elementary school, they require entire lesson units in school on telling time from a clock face.
Beyond that, he argues that pie charts tell us more about the relationship between things than tables of numbers, and a clock face is "the world's most perfect pie chart." But a clock face is not really a pie chart. It does not indicate distribution among categories, as a pie chart does. The arms are not delimiters; they merely indicate position.
