Will Smith's concert crowds are real, but AI is blurring the lines

I was recently sent a link to this recording of a David Bowie & Nine Inch Nails concert, and I got a serious uneasy feeling as if I was on a psychedelic and couldn't quite trust my perception, especially at the 2:00 mark: https://www.youtube.com/watch?v=7Yyx31HPgfs&list=RD7Yyx31HPg...
It turned out that the video was "AI-upscaled" from an original which is really blurry and sometimes has a low frame rate. These are artistic choices, and I think the original, despite being low resolution, captures the intended atmosphere much better: https://www.youtube.com/watch?v=1X6KF1IkkIc&list=RD1X6KF1Ikk...
We have pretty good cameras and lenses now. We don't need AI to "improve" the quality.
Yesterday we went to a store to have a look at a few smartphone for my partner. She primarily wants a good camera above any other parameter. I was seeing her preferring those that were counterfeiting the reality the most: she was like, "look I can zoom and it is still sharp" while obviously there was a delay between zooming and the end result which was a reconstructed, liquid like distorded version similar to the upscaling filters people are using on 8/16bit game console emulators. I was cringing at seeing the person I love the most preferring looking at selfies of picture of us with smoothed faces and a terrible fake bokeh in the background instead of something closer to the reality.
It's kinda funny to aim for 60fps because modern video productions will often have 60fps footage that's too sharp and clean. So they heavily post process the videos. You add the film grain and lower the fps to 30 or even 24 (cinema) so it looks much more natural.
The question is if this is just habitual / taste thing. We most likely wouldn't prefer 24fps if the movie industry started with 50fps.
Over time I noticed everything looks cheaper on their TV.
It was the auto-smoothing.

The extreme blur here was obviously a creative choice by the director/editor, the rest of the video has lower resolution but it's not nearly that bad (which is why Bowie still looks like himself in other parts of the upscaled video).
The process used to upscale the video has no subtlety, it's just "make everything look crisp, even if you have to create entirely made-up faces".
I see this upscaling a lot in Youtube videos about WWII that use very grainy B+W film sources (which themselves aren't using the best sources of) and it just turns the footage into some weird flat paneled cartoonish mess. It's not video anymore, it's an animated approximation.

At 2:04 the original deliberately has everyone on stage way out of focus, and the AI upscaler (or the person operating it) decided to just replace it with an in-focus version sporting what looks like late 90s video game characters. That is terrible.
I had to stop playback or I’m sure I would have thrown up. And I don’t suffer from motion sickness etc.
There’s definitely something “uncanny valley” about it.
> The video features real performances and real audiences, but I believe they were manipulated on two levels:
1. Will Smith’s team generated several short AI image-to-video clips from professionally-shot audience photos
2. YouTube post-processed the resulting Shorts montage, making everything look so much worse
You can see the side-by-side [1] of the YouTube post-processing, and, while definitely altering the original, isn’t what’s causing most of the really bad AI artifacts.
Most of what YouTube appears to be doing is making it less blurry, sometimes successfully, and sometimes not. And, even with that, it is only done on Shorts.

Seriously, who's idea was this? It can't be a money saving feature; surely it costs more to upscale all these videos than to just host the HD version.
And even if you argue it can be used only on low res videos to provide a "better experience", the resulting distortion of reality should be very concerning.
This can backfire, perhaps making people believe that real, important news is in reality AI-generated to brainwash them, thus making people less susceptible, and more disbelieving.
Today on The Verge, GenAI upscaling in YT shorts. Yes, AI is here to stay, but I do hope the icky parts go away soon.

I cannot watch the linked video, but its description quotes “not generative AI”; is The Verge or someone else showing something different?

You actually need a reputation of merit for there to be risk. Hes a rapper, not a saint or Ethicist.
If there's code to stop AI from being trained on AI, I would like to have it from stopping me from seeing it.
