Here's the thing. Traditional silver halide negatives are really 'digital'. At least they consist of crystals that are either turned to silver or not. The tones are created by the number of crystals in any given area. Whereas digital cameras are analogue, at least at the beginning of the imaging chain. Each sensel is a photodiode whose charge is proportional to the intensity of light. Then the voltages thus obtained have to be converted to digital bits in an analogue to digital converter.

I like Bob Johnston’s redefinition! Weren’t many early cave paintings digital? Many were made by or with the aid of digits and many feature digits as their subjects ;-) .

What a fascinating recommendation. Thanks!
