In fairness, I did not say that the transition to 8k was easy or that any "competent film crew" could make a beautiful 8k film or leverage 8k to its max. I said that a competent film crew could soften the look if appropriate. The lazy fix for "too sharp" is to just scale down to 4k or throw a slight blur at the frames. A slightly less lazy fix would be use lenses that yield a softer focus (which I assume some of the insanely expensive film lenses can deliver).

But I wasn't saying it's trivial to leverage 8k well, just that if 8k is too much to deal with in some cases, effectively reducing the resolution seems a tractable problem.
