Write a script for Rick from Rick and Morty where he is telling Morty about his concerns for who will be his new voice actor and whether he will get replaced by an AI voice.
Sure! Here is a potential script:

[Scene: Rick and Morty are walking through a corridor in the spaceship. Rick is worried and Morty looks concerned.]

Rick: Morty, I've been thinking a lot lately.

Morty: About what, Rick?

Rick: My voice actor. You know, the guy who does my voice on the show.

Morty: Yeah, what about him?

Rick: Well, what if he gets replaced by an AI voice? I mean, AI technology is advancing rapidly these days. It's entirely possible that soon AI will be able to replace human voice actors.

Morty: I don't think that's going to happen, Rick.

Rick: You don't know that, Morty. AI voices are getting better and better. They're even starting to sound more human. What if they replace all human voice actors with AI voices?

Morty: I don't think that's going to happen, Rick. People still prefer the sound of a real human voice. Plus, there's still the emotional aspect of human voice acting that AI can't replicate.

Rick: Emotional aspect, huh? That's a good point, Morty. But what if they develop AI that can replicate human emotions too?

Morty: [sighs] I don't know, Rick. I just think we should focus on what's happening right now and not worry too much about the future.

Rick: [pauses for a moment] You're right, Morty. I shouldn't worry about it. I mean, even if my voice actor does get replaced by an AI voice, I'll always be here.

[Scene ends]

I hope that script was what you were looking for, and if not, don't hesitate to correct me or ask for revisions!
This is a fine script, but I'd personally swap Rick and Morty's lines to be more fit for the characters. Morty seems like he'd be the kind of person to be worried by this while Rick would shrug it off
I swapped the characters for you:

[Scene: Rick and Morty are walking through a corridor in the spaceship. Morty is worried and Rick looks concerned.]

Morty: Rick, I've been thinking a lot lately.

Rick: About what, Morty?

Morty: My voice actor. You know, the guy who does my voice on the show.

Rick: Yeah, what about him?

Morty: Well, what if he gets replaced by an AI voice? I mean, AI technology is advancing rapidly these days. It's entirely possible that soon AI will be able to replace human voice actors.

Rick: I don't think that's going to happen, Morty.

Morty: You don't know that, Rick. AI voices are getting better and better. They're even starting to sound more human. What if they replace all human voice actors with AI voices?

Rick: I don't think that's going to happen, Morty. People still prefer the sound of a real human voice. Plus, there's still the emotional aspect of human voice acting that AI can't replicate.

Morty: Emotional aspect, huh? That's a good point, Rick. But what if they develop AI that can replicate human emotions too?

Morty: [pauses for a moment] You're right, Rick. I shouldn't worry about it. I mean, even if my voice actor does get replaced by an AI voice, I'll always be here.

[Scene ends]

I hope this is better.
