Not the case in darktable, and it’s useful at least to see the noise/details trade-off.

It’s useful in photography. 8K is 33 megapixels, which some modern cameras can exceed (whereas 4K is 8 megapixels which every camera exceeds).

“16% fewer travel kilometers”, meaning trains are used massively more often since they typically don’t cover nearly as many kilometers. People would probably chose to take the train more often even if it meant traveling to less distant destinations if the planes were more expensive.
