This was a good meme a year ago but these days it’s out of date. Popular image AIs like Midjourney and Dall-E now do accurate hands the vast majority of the time.
Not really, they still can't do hands and faces reliably, especially DALL-E which hallucinates like mad (not just with hands) and generally has quite a lot of distinctive artifacts on lines and densely packed details. It is possible to fix hands in SD/SDXL 100% of the time, but that's much more involved.
