The problem with AI upscaling is that it does add something. It fills in the details with things that could plausibly be there, regardless of if they are. It's especially dangerous if it's used for something like security footage, where it'll do stuff like make up a face based on a few pixels.
Not a major issue when I’m chilling watching my YouTubes.
Depending on the context it's probably not that bad, but there's plenty of details in youtube videos that people pay attention to, like in news, history, tutorials, educational content, and so on. Even for a fictional story, it could add nonsense that people assume is part of the actual show.
If the original footage is so bad that "nonsense that people assume is part of the actual show" "could plausibly be there", then the problem is not with the AI... it wouldn't be the first time I'm confused by the artifacts in a low quality video.
At worse upscaling will make the video worse. It won't add aliens or some shit to your videos.
With AI upscaling it fills it in based on the training from other images/videos. So it probably won't be an alien, but small details common in other videos that looked similar will also show up in the upscaled videos. If an extra flower shows up in a field of grass it's usually not a big deal, but for some things like faces or symbols, small details can really change the way people interpret it.
I highly doubt the upscaling could do anything close to adding faces or something.
The best it could do with a blurry face like thing is probably just to make it look sharper.
