As though the size of silver halide crystals were the be-all and end-all of photochemical photography. Or the properties of a particular half-tone screen were the be-all and end-all of graphic arts reproduction.
No, they're all just one of several variables involved in their respective processes. They all define resolving-power. They don't define dynamic range. They don't define linearity. So yeah, none of them are the be-all and end-all.
Arguably, the most important characteristic printed on a film package (other than brand/product line) is ISO/ASA (sensitivity), while the most important characteristic on the packaging of a digital camera (other than brand) is megapixels (resolution). So there is a bit of a disconnect in emphasis between film and digital, but neither tells the whole story. I think it's a measure of what was most important going all the way back to the beginning of each medium.
In photochemical photography, it was the need for speed - freezing motion. Characteristics like grain took a back seat - grain was adequate, more or less from the start - just make the plate large (which wasn't hard to do).
In digital photography, speed was more or less adequate from the start. The problem was resolving power - matching or exceeding the resolution of film. Hence the pixel wars.
Let me rephrase:
As if ANY technical consideration were the be all and end all of photography.
