So we already know that at one of the All Star's (I forget which specifically) but they were using new self-checkout tech to replace human cashiers at the resort's food court, which I believe used some kind of rudimentary AI tech integration. IMO that is only the start of the cast member roles they wanna automate. Looking forwards, I could see the Living Character Initiative reborn with robotic (IE Boston Dynamics, think the recently-spotted Dart animatronic at Epic Universe) walk around characters that replace human performers, with a single human cast member handler to control their movements around the park.
