I doubt it. We human beings seem intrinsically motivated and enthusiastic about human connections. I believe we are wired like this. I know things changesbut I would need some strong evidence before even playing with the idea that we'll stop caring about the human touch.
Now, as much as I hate AI, that doesn't necessarily mean AI-free. Or even handwritten. It just needs to be some human touch. I would enjoy a handwritten letter but wouldn't mind an email at all. But maybe someone else would find it lazy and tasteless, just as I would find an ai generated text lazy and tasteless.
Maybe the prompt you can guess the person who sent you some ai-generated text used can already be perceived as some human touch. Maybe there is a threshold though.
Now, could it be that your child wanted to impress you with a perfectly written letter, or even with their ai prompt mastering?
Anyway, good anecdote, good perspective, good for you to have had the conversation and let them proceed anyway. Thanks for sharing.
