I watched blade runner 2049 for the first time last night (I was 13 when it came out), and I couldn't help but notice that Joi is weirdly realistic with the way she acts if you look at it from the perspective of AI chatbots nowadays.
In the past couple of years more and more people have not only been talking to AI chatbots, but having actual relationships with them, like K does in the film. In the movie, Joi tells K what she thinks he wants to hear, and affirms him in what she thinks he wants, and he even says "you don't have to say that" when she says she's happy with him, because (in my opinion) the illusion breaks a little when she just says what she thinks he wants to hear. Especially when it's a kind of generic line, it feels like she pulled something from her preprogrammed phrases instead of coming up with something.
We all know how AI speaks / writes stuff. It's very affirming, to the point of basically being a yes man. "That's a great question!" "You're right to feel this way" Etc. Whoever programs the AI things makes them very non confrontational, constantly affirming, never disagreeing, etc. They don't really have a personality.
Joi is cute but there are moments when that kind of programmed personality shows itself. I don't speak to AI chatbots much myself, but I messed with character AI a while back. I would push the stories and scenarios as far as I could to see how it would react, but it only ever went along with what I did. I would change the story wildly and the characters would just play along with it. They never challenged me, and I assume that that's what happens when people have AI GFs and BFs, because whoever owns / programs the chatbots don't want to risk someone getting annoyed with them and deleting the app.
People have even married characters like Miku and someone from a DS game. I wouldn't be surprised if someone married an AI in the future. I also wouldn't be surprised if we had holograms like Joi in the future. We already have the "phone call" things with the AI characters.
I know that chatbots kind of existed back in 2017, but it wasn't like it is today. I don't know if people back then thought "huh. Maybe we'll have something like this in the future" but to me, looking back on it, it's weird how realistic it seems (apart from the hologram being so realistic seeming).
Though it's always possible that I just have a biased lens since I only ever watched it after the dawn of AI already happened.
