You really don’t need any kind of fancy AI algorithm to associate different keyframes with different areas of the photo. This could be done using any number of standard computational photography techniques based on straightforward criteria such as exposure, motion blur, etc. etc. For this reason I’m skeptical of your claim that ‘HDR in older phones would have only merged/blended the images resulting in ghosting…or blurring’. Even if we assume this is true for the sake of argument, you undermine your own point here, as ghosting and blurring are also distortions of reality. You’re apparently ok with a photo showing a person with ‘more than two arms’, but not ok with a photo combining slightly different time-slices of the same scene (which is actually any photo taken using a focal plane shutter above flash sync speed :)). You're entitled to your subjective preference there, but I certainly don't share it myself.
