I'm genuinely frightened that they're going to fix the hand problem soon.

I hate to break it to you, but that's been varying degrees of solved for over a year. Most AI slop that just contains ludicrous basic errors is left unfixed because the people who spam AI slop are principally just incredibly stupid, lazy chuds slamming the treat button like it's a gacha pull, but even something as basic as automatic1111 or its relatives allowed manual inpainting to reroll broken parts of the image, then added optional automatic secondary processes to detect faces and hands and run an automated inpainting process to fix them with dedicated "fix faces and hands" models.

Now currently relevant open models range from "sometimes it doesn't fuck up" to "the only tell is that proportions are subtly off and that sometimes there are continuity issues that give away that there's not any sort of reality behind the image nor even an internal model of what is there in places you can't directly see, but it's less glaring than it used to be" and it's only getting more horrifying. Looking at "realistic" models always makes me feel sort of sick, even beyond the rote response I feel whenever I look at civitai.
