Wouldn't discretion "just" be a really good rules engine?

No, they are moderated by arbitrary company moderation policies not humans with independent thoughts.

AI can do exactly that.

> Heavily moderated by humans with discretion.

Pretty sure both of the above have extensive automation in their moderation.

The bulk of moderation work is things which are easy and obvious.

The correct way to moderate is automation with certainty falling back to humans with discretion.

The new frontier of moderation should be blocking illiterate comments, as in the commenter is replying as though they didn't read or read and didn't understand.

I'd rather be censored by an AI than a reddit mod.
