Sure, and my camera can do bird eye detection and whatnot too, but that's a very lightweight model running in-body. Probably just a fine-tuned variant of something like YOLO.

I've seen only a couple of papers from Google talking about stacking multiple frames from a DSLR, but that was only research for improving mobile phone cameras.

Ironically, some mobile phones now have more megapixels than my flagship full-frame camera, yet they manage to stack and digitally process multiple frames using battery power!

This whole thing reminds me of the Silicon Graphics era, where the sales person would tell you with a straight face that it's worth spending $60K on a workstation and GPU combo that can't even texture map when I just got a Radeon for $250 that runs circles around it.

One industry's "impossible" is a long-since overcome minor hurdle for another.

A DSLR and mobile phone camera optimize for different things and can't really be compared.

Mobile phone camera's are severely handicapped by the optics & sensor size. Therefore to create a acceptable picture (to share on social media) they need to do a lot of processing.

DSLR and professional camera's feature much greater hardware. Here the optics and sensor size/type are important it optimize the actual light being captured. Additionally in a professional setting the image is usually captured in a raw format and adjusted/balanced afterwards to allow for certain artistic styles.

Ultimately the quality of a picture is not bound to it's resolution size but to the amount and quality of light captured.
