A computer cannot understand concepts like what hands actually are, it just has an idea of what hands are supposed to look like. You can show it a million pictures of hands, but at the end of the day, it will never know what a hand is or how a hand is meant to move or bend, and this applies to most things. To some degree, AI "art" will likely always be flawed, and I believe that there will always be some way to tell. At least I hope.
Specifically size 1 Slimes- they are hostile, but have 0 attack damage, meaning I have plenty of time to build up with the existing blocks, collect wool from the roof, and then tower out.
