There's AI that can sometimes do hands okay. It still often fucks up, so a human has to curate the work. And ideally selectively prompt the AI to regenerate parts of the image until the whole thing is perfect. I think Midjourney has the best performance so far. You can take a look for yourself in one of the many AI art communities. They're sadly not as active here as they were on Reddit, but there's imageai and stablediffusion communities (I forget the instance)
