The only AI I’ve heard that is convincing is the Ben Solo one. The rest just aren’t there yet.
Another thing worth mentioning about the whole “sensed the death of her son” thingy is that the film is built around it. Leia’s body doesn’t vanish until Ben’s does because that’s when she’s completed her “Jedi path”. Yes, it may be stupid, but it’s just the way they made the film.
