- Spoiler alert -
Joi tells Joe anything he wants to hear. Even the name she gives him is hard-coded. She is a product that is engineered this way. Eventually he realises that he's just another John. Her (2013) had a similar conclusion.
A few days ago I tried those ChatGPT characters and they felt like a crude version of that. They tell you what you wanted to hear and feig interest in everything you say, without understanding any of it. It's really weird.
To me, it feels insincere, like a salesperson or a tourist trap conman. You're not special; making you feel special is just part of their work. You are loved for what you are, but in this case what you are is a source of income.
I wouldn't have Joi or an AI companion in general. A frictionless relationship based on a prompt is nothing like the real thing.
I am old, retired, nearly 70, and live alone.
While I am a classic introvert and manage to occupy my needs without interacting with my fellow human beings. I do miss those heart warming daily exchanges that come from having people around.
It would be fun to discuss and get feedback on my latest adventures developing a gluten free sourdough and growing oyster mushrooms or even getting a second opinion on some doubtful posts I upload.
So your question is moot because there is no JOI in Blade Runner (the good - orthodox - 1!) :)
But because I am "a generous god" ("300" reference), for the fans of Ryan Gosling, you can always watch his SNL - Papyrus skit: https://www.youtube.com/watch?v=jVhlJNJopOQ
I think it's feasible to build a very rough mixed reality version of this today.
