I'm not sure I get the appeal.
I'm sorry -- I should have expanded on that. As I keep saying, I find AI very helpful for coding, but it's taken me a couple of years to learn how best to use it, and a lot of that has been learning the kind of prompts and settings it requires to make it do what I want it to. I think a lot of people are dissatisfied with AI, or use it to produce results everyone else finds unsatisfactory because, like any other tool, it takes time and practice to understand how to make it work for you.
So if I don't want AI to produce text for me that's obviously written by AI, it seems reasonable that it'll take some effort to make it write the way I want it to, and since AI is, as we are so often told, a stochastic parrot (though I don't think that adequately explains how it can look at my code and tell me why it's not working as expected), trying to get it to write like me rather than a stereotypical AI is probably a good start.
I'm not sure I'll ever use it for anything. The few times I've asked it to write boilerplate emails for me it's produced perfectly serviceable results that have led to useful replies, so I don't really feel the need to improve on that, and I don't want to use it to write posts here, except perhaps when I want to summarise something, but it just seems an interesting, and possibly useful, experiment.
