Remastering can screw up intent with something as simple as color grading.

But there is a line here. An editor that's using simple tools knows exactly what they're changing, and if they're using simple frame-global tools then they're not introducing anything that wasn't already there.

If you throw an AI at things, it will try to guess what things in the image are, and make detail adjustments based on that.

So that's three categories of edit, easily distinguished: human making frame-global changes, human deliberately changing/adding details, AI changing/adding details in a way that's basically impossible to fully supervise.

It sounds like they accept category 1 in remastering, even though it's not foolproof, and reject 2 and 3.

No, "AI" is absolutely not uncontrollable magic that does something you don't want sometimes. It's not an issue really, you always have arbitrarily granular control of the end result, with ML tools or not. You can train them properly, you can control the application, you can fix the result, you can do anything with it. It's the usual VFX process, and it's not the only tool at your disposal.

The problem is that remasters don't make a lot of money, so instead of a properly controlled faithful representation (or a good rethinking) it's typically a half-assed job with a couple filters run over the entire piece. Another issue is that you now have two possibly conflicting intents - one from the original and another from the remaster. ML haven't changed anything in here, it's always been like that.

You can't tell what specific textures it's trying to replicate when it's enhancing detail. It's not magic, but the specifics are uncontrollable.

Sure, my point is that proper remastering is not just applying a couple ML filters. If you're doing that you should either do this selectively or fix the result by other means, i.e. the same thing you would do with dumb processing. This is a labor intensive VFX work, feasible for a new movie but not feasible for a remaster.
