> Plenty of people, myself included, get more instant meaning from a digital readout.
More from outside knowledge than from the digital readout itself. There's no way to tell from a digital readout there are 60 minutes in an hour or seconds in a minute, or that there's a 12-hour period that means something (and no hints to guess.) There's no evidence that the time represented on a digital readout changes at a constant rate or is sequential and doesn't jump around or go faster sometimes and slower others. Everything on an analog clockface is just there.
If you found an alien digital clock written in alien language, it would take you forever to figure out anything about it; it would take a while to figure out anything useful even if you knew it was a clock. If you found an alien analog clock, it would be immediately obvious what it was and what it was doing, and you could use it to help you understand the alien digital clock.
edit: also, when your alien digital watch did the equivalent of jumping from 12 to 1, it would throw everything off, especially if there were a different symbol for 1 second or 1 minute that there was for 1 hour. An analog clock visually explains the transition between 12 and 1.
I think all this stuff is obvious, I'm confused about the argument being made that it's not. There's just less information on a digital readout. I feel like I'm trying to explain that movies have more information than movie scripts, but Kolmogorov would say to compress them both and compare the filesizes.
