No computer algorithm can accurately reconstruct data that was never there in the first place.
Ever.
This is an ironclad law, just like the speed of light and the acceleration of gravity. No new technology, no clever tricks, no buzzwords, no software will ever be able to do this.
Ever.
If the data was not there, anything created to fill it in is by its very nature not actually reality. This includes digital zoom, pixel interpolation, movement interpolation, and AI upscaling. It preemptively also includes any other future technology that aims to try the same thing, regardless of what it's called.
Hold up. Digital zoom is, in all the cases I'm currently aware of, just cropping the available data. That's not reconstruction, it's just losing data.
Otherwise, yep, I'm with you there.

Digital zoom makes the image bigger but without adding any detail (because it can't). People somehow still think this will allow you to see small details that were not captured in the original image.
Also since companies are adding AI to everything, sometimes when you think you're just doing a digital zoom you're actually getting AI upscaling.
There was a court case not long ago where the prosecution wasn't allowed to pinch-to-zoom evidence photos on an iPad for the jury, because the zoom algorithm creates new information that wasn't there.
