I rant about everyone complaining about Apple decision to call their rotary encoder on the Apple Watch a “Digital Crown”.
On mechanical watches, the dial used to adjust the time is called a Crown. It’s always been called that. So in the case of the Apple watch, the crown is not a mechanical one, but a digital one. Gray code is digital. They named it literally exactly what it is. (other than the electronics terminology for it, which is too long and cumbersome to use for marketing)
