This was a legal issue during the Kyle Rittenhouse trial. It wasn't even AI upscaling it was simply how modern desktop/video software fills in details via smoothing in between frames when you slow something down or process it.
So evidence pushed by one of the legal teams which tried to use a highly zoomed in shot on an iPad of a CCTV camera of a parking lot to prove (or disprove I can't remember) a gun was held was called into question. The lawyers had an IT expert which helped dismiss it.
So when it comes down to it when it matters there's still sanity.
Conspiracy theorists also didn't need tech to believe in nonsense before anyway. So it's mostly shades of grey.
when we see how many bad pictures and videos each of us can take just to get one good one, and the crazy expressions on our faces, I'm highly skeptical of "evidence" photos. And slow motion might be handy for seeing particular details like "knee touches ground, ball out of bounds", but otherwise slow motion is highly misleading, making fleeting facial expressions look intentional, etc. If slow motion is used for evidence, it should always be followed by several viewings at normal speed to unconvince you of false impressions.
