That’s pretty cool. Of course Christopher Nolan would insist on editing on film. I bet Tarantino and a few others would as well. In the case of laser printing vs optical printing, he’s probably right, especially at IMAX scale. And you’re absolutely right that he’s choosing it because it’s the highest possible fidelity, whereas someone like Tarantino chooses film for sentimental, kitsch, and artistic reasons. Apparently digital IMAX is still only about 4k at best. In the audio world though, analog DACs really are perfect reproduction many times beyond what is perceptible in sound. Compared to cutting to vinyl from tape, or even transferring from tape to tape, digital is orders of magnitude higher fidelity to the source signal. There’s lots of reasons to love analog audio, but higher measurable fidelity is not among them.
