Court Bans Use of 'AI-Enhanced' Video Evidence Because That's Not How AI Works (gizmodo.com)

A judge in Washington state has blocked video evidence that’s been “AI-enhanced” from being submitted in a triple murder trial. And that’s a good thing, given the fact that too many people seem to think applying an AI filter can give them access to secret visual data.

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.

In my first year of university, we had a fun project to make us get used to physics. One of the projects required filming someone throwing a ball upwards, and then using the footage to get the maximum height the ball reached, and doing some simple calculations to get the initial velocity of the ball (if I recall correctly).

One of the groups that chose that project was having a discussion on a problem they were facing: the ball was clearly moving upwards on one frame, but on the very next frame it was already moving downwards. You couldn't get the exact apex from any specific frame.

So one of the guys, bless his heart, gave a suggestion: "what if we played the (already filmed) video in slow motion... And then we filmed the video... And we put that one in slow motion as well? Maybe do that a couple of times?"

A friend of mine was in that group and he still makes fun of that moment, to this day, over 10 years later. We were studying applied physics.
