This is the first I have heard of AI upscaling. If it makes people happy, the good for them. It's always great when people watch great content like this long after it aired.
Personally, I prefer to stick with the originals. In this case, DVD rips since i no longer watch DVDs. If the streaming versions have been updated, then I watch those just fine. I don't care about the difference between Blu-ray or standard DVD. No need for special processing.
It's the stories that matter most to me.
I don't watch 4k television. I don't have dolby surround sound. When I update hardware, I usually disable various technologies that supposedly make the experience better. (Like that feature that makes everything look like a soap opera).
Things like film grain don't bother me. It's what I grew up with. I always watch media with captions. I like foreign films and television. Black and white can be great. Etcetera.
The story and great acting. That's what I love.
